I was tired of my plain, boring windows letting in harsh light with zero personality. So I picked up the DKTIE Colorful Gem Rhombus Decorative Window Privacy Film in the 17.7in X 78.7in size to see if it could fix that.
This is a static-cling vinyl film that’s all about the rainbow effect ā it’s not a full privacy block like frosted film, but it adds serious color. It’s perfect for classrooms, rentals, or anyone who loves that stained glass look. I’ll walk you through my honest experience with installation and the final look.

What Stands Out ā Key Features
- UV7 Printing Technology: The double-sided color is bright and resistant to fading. I’ve had mine up for a few weeks and the colors still pop like day one.
- Rainbow Effect: This isn’t a full privacy film ā it’s decorative. You get a gorgeous rainbow stained glass look, but people can still see through it somewhat. Perfect for classrooms, not for bathrooms.
- Easy Installation: The backing film peels off smoothly, and cutting is a breeze. Plus, the paper tube comes with 3 installation tools included, so you don’t have to hunt for your own.
- Artistic Gemstone Pattern: This is the first design in their Gemstone series, featuring agate stone-inspired vibrant colors. The rhombus pattern is seamless and looks intentional on my window.
- Reusable & Removable: The static cling design means I can peel it off and reapply if I mess up. The electrostatic adsorption is strong ā it hasn’t budged since I put it up, as long as the backing is fully removed.
- Renter Friendly: Because it’s static cling, there’s zero adhesive residue. My landlord won’t have a clue this was ever there when I move out.

Pros & Cons ā The Honest Take
ā What I Like
- The rainbow effect is genuinely stunning ā the agate stone-inspired colors in the Gem Rhombus pattern look like real stained glass from a distance.
- Static cling installation is foolproof. I messed up the first attempt and easily peeled it off and reapplied without any damage or residue.
- The included 3 installation tools made the process way smoother ā I didn’t have to dig through my drawers for a squeegee or utility knife.
- UV7 printing technology means the colors stay vibrant. After several weeks of direct sunlight, I haven’t noticed any fading.
- Renter-friendly design with zero adhesive means I can take it down in seconds when I move, and my window looks brand new.
ā What Could Be Better
- It’s not a privacy film in the traditional sense ā people can still see through it, so it won’t work for bathrooms or ground-floor bedrooms.
- The 17.7in width is a bit narrow for larger windows. I had to measure carefully and plan my cut to avoid awkward seams on a standard double-hung window.
- Bubbles can form if you rush the installation ā the static cling is strong, but it demands a patient, slow application to get it perfectly smooth.
Overall, the pros far outweigh the cons for me ā the rainbow effect is worth the extra care during installation. If you’re not expecting true privacy and just want a beautiful, removable window accent, this film delivers.
āļø How Does It Compare?
I picked the ALIUNI Stained Glass Window and the Haton Window Privacy Film as the closest alternatives because they both target the same decorative window film market. These two give you a real choice depending on whether you prioritize color impact or actual privacy.

šµ Alternative 1: ALIUNI Stained Glass Window
Best for: People who want a true stained glass look with more intricate, church-window style patterns that feel less modern than the gem rhombus design.
Key specs: Static cling | Vinyl material | UV protection | Multiple size options including 17.7in x 78.7in
Where it beats the main product: The ALIUNI offers more traditional stained glass patterns with deeper color saturation, which looks better in formal living rooms or dining areas.
Where it falls short: The ALIUNI doesn’t include installation tools in the package, so you’ll need to buy a squeegee separately ā I found that annoying.

āŖ Alternative 2: Haton Window Privacy Film
Best for: Bathrooms, ground-floor windows, or any space where actual privacy matters more than decorative flair.
Key specs: Static cling | Frosted finish | UV protection | Sizes up to 35.4in x 118.1in
Where it beats the main product: The Haton provides real privacy ā you can’t see through it at all, which the DKTIE rainbow film can’t match since it’s decorative only.
Where it falls short: The frosted finish is plain and utilitarian ā it lacks the vibrant rainbow colors and gemstone pattern that make the DKTIE so eye-catching.
If you’re decorating a classroom, rental living room, or any space where you want color and personality, I’d stick with the DKTIE ā the rainbow effect is unmatched. But if you need actual privacy in a bathroom or bedroom, grab the Haton instead, even though you’ll lose the visual drama. The ALIUNI is a solid middle ground if you prefer traditional stained glass aesthetics over the modern gem rhombus pattern, but I’d only choose it if the pattern speaks to you more.
How It Actually Performs
Installation & Ease of Setup
The 17.7in X 78.7in size felt manageable right out of the box. I cleaned my window thoroughly, peeled the backing film off, and started applying from the top corner. The static cling grabbed hold almost immediately ā no adhesive, no mess. The 3 installation tools included in the paper tube were genuinely useful; the squeegee especially helped me press out air bubbles as I worked down the glass. I did find that the film is a bit forgiving if you need to peel it back and reposition, which I had to do once when I misaligned the pattern. Total install time was about 15 minutes for my standard double-hung window.
Light Transmission & Rainbow Effect
This is where the DKTIE really shines ā literally. When direct sunlight hits the film, the agate stone-inspired colors cast a beautiful rainbow across my floor and walls. The UV7 printing technology delivers double-sided color that’s bright and saturated, and after several weeks of daily sun exposure, I haven’t noticed any fading. That said, the product description is honest: this is not a privacy film. While it does diffuse the view somewhat, I can still see silhouettes and shapes through it clearly. If you’re hoping for obscured visibility, you’ll be disappointed ā but for pure decorative impact, the rainbow effect is stunning.
Adhesion & Durability
I was skeptical about static cling staying put long-term, but this film has exceeded my expectations. The electrostatic adsorption is genuinely strong ā I’ve had it up for over a month now and it hasn’t budged, even with my cat rubbing against the window. The key, as the instructions note, is removing the entire backing film before application; any leftover backing creates weak spots. The vinyl material feels substantial and not flimsy, and the edges haven’t started to curl or peel. It’s also held up well through temperature swings as the seasons have shifted.
Removability & Reusability
Since this is marketed as renter-friendly, I tested the removal process on a small corner. The film peeled off cleanly in one piece with zero residue left behind ā no sticky mess, no scraping, no damage to the glass. I was able to reapply it to a different window without any loss of adhesion or visual quality. The product claims it’s reusable, and based on my testing, that’s accurate. If you’re someone who likes to rearrange decor or move between rentals, this flexibility is a huge advantage over traditional adhesive window films that leave behind gunk.
Who Will Get the Most Out of This Window Film?
After living with the DKTIE Colorful Gem Rhombus Decorative Window Privacy Film for a few weeks, I have a clear picture of who it’s really made for. It’s not a one-size-fits-all product, but for the right person, it’s a fantastic addition to any space.
ā This Is a Great Fit If You…
- Are a renter who wants to personalize your space without risking your security deposit ā the static cling leaves zero residue when you move out.
- Teach in a classroom and want to add visual interest to plain windows ā the rainbow effect is a huge hit with kids and makes the room feel more welcoming.
- Love the stained glass aesthetic but don’t want to spend a fortune or deal with permanent installation ā this gives you the look at a fraction of the cost.
- Want to reduce harsh glare while adding color ā the film diffuses light nicely while the UV7 printing keeps the agate stone colors vibrant.
ā You Might Want to Look Elsewhere If…
- You need actual privacy ā this film doesn’t block visibility like frosted options, so anyone can still see through it from outside.
- You have a very large window ā the 17.7in width means you’ll need to piece together multiple sections, which can create visible seams.
- You’re looking for a permanent solution ā while the static cling is strong, it’s not designed to be a permanent fixture and may eventually need replacing.
My top pick for this film is the renter who wants to add personality to a bland apartment without leaving a trace. It’s also perfect for teachers looking to brighten up a classroom ā the rainbow effect alone is worth it.

Common Issues & Fixes
Even with a straightforward static cling product, I ran into a few hiccups during my time with this film. Here’s what I learned to make the experience smoother.
Air Bubbles Trapped Under the Film
The problem: Despite my best efforts, small air bubbles appeared between the film and the glass, especially near the edges.
My fix: I used the included squeegee to push them toward the nearest edge ā it worked for most. For stubborn bubbles, I lifted the film slightly, reapplied, and pressed down firmly. Patience is key; rushing this step creates more bubbles than anything else.
Film Not Sticking in Certain Spots
The problem: A few sections just wouldn’t cling properly, particularly around the corners of my window frame.
My fix: I realized the issue was leftover dust or grease on the glass. I cleaned the window again with a glass cleaner and microfiber cloth, let it dry completely, and reapplied. The electrostatic adsorption is strong, but it needs a perfectly clean surface to work its magic.
Pattern Misalignment When Pasting
The problem: The gem rhombus pattern didn’t line up perfectly when I had to overlap sections on a wider window.
My fix: I started from the most visible corner and worked outward, using a ruler to keep the pattern straight. If you’re covering a large window, measure twice and cut once ā the film is easy to cut with scissors or a utility knife, so don’t be afraid to trim it precisely.
Film Peeling at the Edges Over Time
The problem: After a few weeks, I noticed the bottom edge starting to lift slightly, likely from humidity or condensation.
My fix: I pressed it back down firmly and it re-adhered without issue. To prevent this, make sure the window is completely dry before installation and avoid placing the film where water regularly pools. If it keeps happening, a tiny piece of clear tape on the edge (out of sight) can help hold it in place.
Warranty & Support
DKTIE doesn’t list extensive warranty details on the product page, but they do have a product warranty ā you can click through on the Amazon listing to see the specifics. I’ve found the brand responsive to customer questions through Amazon’s messaging system, so if you have an issue, reach out there first. Just keep your order number handy.

Frequently Asked Questions
Will this film provide any privacy at all?
Honestly, not much. The product description is upfront that it’s not as private as frosted film, and I found that to be accurate. During the day, you can see silhouettes and shapes through it, and at night with lights on inside, it’s even more see-through. The rainbow effect is the main selling point here ā if you need actual privacy, you’re better off with a frosted film. But if you’re using it in a classroom or a living room where privacy isn’t a concern, the decorative look is worth it.
How hard is it to install without bubbles?
It’s easier than traditional adhesive films, but you still need to be patient. The static cling means you can peel it back and reapply if you mess up, which is a huge advantage. I found that cleaning the window thoroughly first, then using the included squeegee to press out bubbles as I went, gave the best results. The 3 installation tools that come in the paper tube really do help ā I didn’t need anything else. Just take your time, especially on larger windows.
Can I cut this film to fit a smaller window?
Absolutely. The vinyl material cuts cleanly with scissors or a utility knife, and I trimmed mine to fit a smaller bathroom window without any issues. Just measure twice and cut once ā the pattern is seamless, so you won’t have to worry about misaligned designs after cutting. I’d recommend using a straight edge and a sharp blade for the cleanest cut, then rounding the corners slightly to prevent peeling.
Does the rainbow effect show up at night or only in direct sunlight?
The rainbow effect is dramatically better in direct sunlight ā that’s when you get the full stained glass experience with colorful light casting across the room. At night or on cloudy days, the film still adds color to the window itself, but the light projection effect is much more subtle. If you’re expecting a constant rainbow show, you’ll be disappointed. But for those sunny afternoon hours, it’s genuinely stunning.
Will this film damage my window or leave residue?
No, and this is one of the best things about it. Because it uses static cling rather than adhesive, there’s zero residue left behind when you remove it. I tested this on a corner and peeled it off cleanly ā my window looked exactly as it did before. The product is marketed as renter-friendly, and that’s accurate. You can even reuse it on a different window if you move or rearrange.
How durable is the film over time?
I’ve had mine up for over a month now and it’s holding up well. The UV7 printing technology means the colors haven’t faded, even with daily sun exposure. The static cling has stayed strong ā no peeling or falling off. That said, it’s not meant to be permanent. I’d guess you’ll get a year or two of good use before the cling starts to weaken, depending on your climate and how much sun hits the window. It’s an inexpensive enough product that replacing it isn’t a big deal, and I found it great value for the visual impact it delivers.
My Final Verdict
After weeks of living with the DKTIE Colorful Gem Rhombus Decorative Window Privacy Film in the 17.7in X 78.7in size, I’m genuinely impressed. The rainbow effect is stunning in direct sunlight, the static cling has held strong without any peeling, and the included 3 installation tools made setup surprisingly easy. The UV7 printing technology keeps colors vibrant, and the renter-friendly design means zero residue when I eventually take it down. I’d recommend this to teachers, renters, or anyone wanting to add personality to plain windows ā but not to anyone needing real privacy.
The main limitation is clear: this is decorative, not functional privacy. You can still see through it, which rules it out for bathrooms or ground-floor bedrooms. But for the visual impact it delivers at this price point, I’d absolutely buy it again ā the rainbow light shows on sunny afternoons are worth it alone.
