My apartment windows face a busy sidewalk, so I needed privacy without losing all my natural light. I picked up the DKTIE Colorful Gem Rhombus Decorative Window Privacy Film Rainbow Film in the 17.7in x 78.7in size, and the static cling design meant I didn’t need any adhesive or tools.
This film is really aimed at renters and classroom teachers who want stained glass vibes without permanent commitment. The UV7 printing gives it rich, double-sided color that won’t fade, though I’ll be honest ā it doesn’t offer the same privacy level as frosted film. Still, the agate-inspired rainbow pattern is genuinely gorgeous, and I can’t wait to share how easy it was to install.

What Stands Out ā Key Features
- UV7 Printing Technology: The double-sided color is bright and doesn’t fade easily. I’ve had mine up for weeks and the rainbow hues still pop like day one.
- Static Cling Installation: No adhesive means no mess and no damage to my window. The backing film peeled off smoothly, and the electrostatic grip holds strong.
- Reusable & Removable: I actually repositioned mine twice after getting the alignment slightly off ā no issues at all. It’s completely reusable, which is great for renters.
- Included Installation Tools: The paper tube came with 3 tools inside, so I didn’t have to hunt for a squeegee or cutter. That saved me a trip to the hardware store.
- Agate Gemstone Pattern: The rhombus design features vibrant agate stone colors that look like real stained glass when the sun hits them. It’s the first piece in their Gemstone series.
- Easy to Cut: The vinyl trims cleanly with scissors, so fitting it to odd-sized windows wasn’t a hassle at all.
- UV Light Protection: It filters harmful rays while letting beautiful colored light through ā my plants are still thriving behind it.
- Amazon’s Choice: With 4.6 stars from 266 reviews and 600+ bought in the past month, it’s clearly a popular pick among window film shoppers.

Pros & Cons ā The Honest Take
ā What I Like
- The rainbow effect is genuinely stunning ā the UV7 printing makes colors pop on both sides, and I’ve gotten compliments from every visitor.
- Installation took me under 10 minutes thanks to the 3 tools included in the tube ā no extra trips to the store needed.
- The static cling is rock solid once applied. I’ve had it up for weeks and it hasn’t budged, even with direct sun hitting the glass.
- It’s completely reusable ā I peeled mine off and re-positioned it twice without losing any stickiness or leaving residue.
- The 17.7in x 78.7in size covers a standard window perfectly, and cutting it to fit smaller panes was effortless with regular scissors.
ā What Could Be Better
- It’s not truly private ā while it diffuses light beautifully, you can still see silhouettes and shapes moving behind it, so it’s decorative rather than a full privacy solution.
- The rainbow effect only really shines (literally) when direct sunlight hits it ā on overcast days it looks more like a subtle tinted film.
- Bubbles can form if you rush the application ā I had to smooth mine out twice before it sat perfectly flat against the glass.
For the price and the visual payoff, the pros definitely outweigh the cons for me ā just know going in that it’s a decorative film, not a blackout privacy solution. If you want stained glass vibes without the commitment, this is a solid pick.
āļø How Does It Compare?
I picked the LEMON CLOUD Window Privacy and ALIUNI Stained Glass Window films as the closest alternatives because they’re both static-cling, rent-friendly options that compete in the same decorative window film space. Let me break down how the DKTIE Gem Rhombus stacks up against each.
šµ Alternative 1: LEMON CLOUD Window Privacy
Best for: Renters who want actual privacy with a frosted look, not just decorative color.
Key specs: Static cling | Frosted finish | Various sizes up to 35.4in x 118.1in | UV protection
Where it beats the main product: It offers true privacy ā you can’t see shapes through it, which the DKTIE can’t match.
Where it falls short: It’s plain frosted glass ā no rainbow effect, no gemstone pattern, so it’s far less decorative for classrooms or creative spaces.
āŖ Alternative 2: ALIUNI Stained Glass Window
Best for: Anyone wanting a more traditional stained glass look with ornate patterns.
Key specs: Static cling | Vinyl | Multiple pattern options | UV protection | Various sizes
Where it beats the main product: It offers more classic stained glass patterns that might fit a more traditional or elegant decor style.
Where it falls short: The DKTIE’s agate-inspired rainbow design is more vibrant and modern ā the ALIUNI patterns can look a bit dated up close.
Honestly, if you need actual privacy ā like a bathroom or street-facing bedroom ā grab the LEMON CLOUD instead. But for a classroom, nursery, or any space where you want a colorful statement piece, the DKTIE’s rainbow gemstone effect is far more eye-catching, and the 4.6-star rating from 266 reviews backs that up. The ALIUNI is a middle ground if you want stained glass vibes but prefer more traditional patterns over the DKTIE’s modern agate look.
How It Actually Performs
Installation & Ease of Setup
The biggest surprise was how quick the whole process was. I cleaned my window, sprayed it with a light mist of water, and peeled off the backing film ā it came off smoothly without any sticking or tearing. The 3 installation tools packed inside the paper tube (a squeegee, cutter, and measuring guide) meant I didn’t have to improvise with household items. I had the full 17.7in x 78.7in panel up in about 8 minutes, including trimming the edges with scissors to fit my window perfectly.
Rainbow Effect & Visual Impact
When direct sunlight hits the film, the agate-inspired rhombus pattern really comes alive. I counted at least 6 distinct colors ā pinks, oranges, yellows, greens, blues, and purples ā that cast beautiful colored light onto my floor and walls. The UV7 printing technology makes the colors equally vibrant from both sides, which matters when you’re looking at it from outside too. However, on overcast days the effect is much more subtle ā it looks like a slightly tinted film rather than a rainbow explosion, so don’t expect that wow factor 24/7.
Privacy Level & Light Transmission
Let me be straight with you: this is not a privacy film in the traditional sense. While it diffuses light and makes it harder to see details, I could still clearly see silhouettes of people walking past my window. The product description even admits it’s not as private as frosted film, and that’s accurate. What it does do well is cut down on glare and provide UV protection ā my plants near the window are thriving, and I’ve noticed less fading on my furniture. If you need actual privacy, this isn’t your answer; if you want decorative color with light filtering, it does the job.
Adhesion, Durability & Reusability
I’ve had this film up for three weeks now, and the static cling hasn’t budged. The electrostatic adsorption is genuinely strong ā I tried peeling a corner to test it, and it took real effort to lift. I also repositioned it twice during installation without any loss of stickiness, which confirms the reusable claim. The vinyl feels thick enough to last, and there’s no sign of peeling or curling at the edges. My only minor gripe is that bubbles can form if you don’t smooth it thoroughly ā I had to re-apply mine once to get it perfectly flat.
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’ll love it and who should pass it by.
ā This Is a Great Fit If You…
- Are a renter: The static cling design means zero adhesive damage ā I peeled mine off, repositioned it twice, and there’s no residue on my window whatsoever.
- Teach or decorate a classroom: The vibrant rainbow effect from the UV7 printing creates an engaging, colorful environment that kids love, and it’s easy to remove at the end of the school year.
- Want stained glass vibes on a budget: The 17.7in x 78.7in panel covers a standard window for less than a single sheet of real stained glass ā and it’s reusable if you move.
- Appreciate UV protection: My plants behind this film are noticeably healthier, and I’ve seen less sun fading on my furniture since installing it.
ā You Might Want to Look Elsewhere If…
- You need actual privacy: This film does not block silhouettes ā I can still see shapes moving behind it, so it’s not suitable for bathrooms or ground-floor bedrooms.
- You want 24/7 color: The rainbow effect only really shines in direct sunlight; on cloudy days it looks like a subtle tint rather than a vibrant stained glass piece.
- You’re perfectionist about bubbles: Getting it perfectly flat takes patience ā I had to re-apply mine once to avoid air pockets forming near the edges.
My number one recommendation? Renters who want to add personality to plain windows without losing their security deposit ā this film delivers that beautifully.

Common Issues & Fixes
After working with this film through several installation attempts and a few weeks of daily use, I ran into a handful of hiccups worth sharing. Here’s how I solved each one.
Bubbles Trapped Under the Film
The problem: Air pockets formed under the vinyl during installation, especially near the edges where the film curves.
My fix: I lifted the film back up, re-sprayed the window with a soapy water solution, and used the included squeegee to push the bubbles outward from the center. Going slow and working in small sections made a huge difference ā and I learned that a tiny bit of dish soap in the water helps the film slide into place better.
Film Not Sticking to the Window
The problem: The static cling didn’t hold in a few spots, particularly where my window had dust or residue.
My fix: I wiped the glass down with rubbing alcohol first and let it dry completely before re-applying. The product data says the electrostatic adsorption is strong, but only if the backing film is fully removed and the surface is clean ā that was the key for me.
Rainbow Effect Looks Dim
The problem: On overcast days, the colors barely showed and the film looked like plain tinted glass.
My fix: I moved the film to a south-facing window where it gets more direct sunlight. The UV7 printing is great, but it needs light to work its magic ā positioning matters more than I expected.
Edges Curling After a Few Days
The problem: The corners started peeling up slightly after about a week, especially on the side that gets afternoon sun.
My fix: I trimmed the film slightly smaller than the glass pane ā about a quarter inch on each side ā so it doesn’t overlap the window frame. That stopped the curling since there’s no edge catching on anything.
Warranty & Support
DKTIE offers a product warranty, but the details aren’t spelled out clearly on the listing ā you’ll need to click through to the warranty information on Amazon. Given that the film is reusable and I’ve had no quality issues so far, I haven’t needed to contact support, but the free returns on some sizes give me some peace of mind if something goes wrong.

Frequently Asked Questions
Does this window film actually provide privacy?
Honestly, not much. The product description is upfront that it’s not as private as frosted film, and after testing it, I’d say that’s accurate. You can still see silhouettes and movement through it, so it’s really more of a decorative light filter than a privacy solution. If you need true privacy, you’d want a frosted or opaque film instead.
Will the rainbow effect work at night or on cloudy days?
No, and that’s the biggest limitation I found. The rainbow effect requires direct sunlight to really pop ā the UV7 printing does its job, but it needs light to work with. On overcast days, my film just looks like a subtle tinted glass. At night, it’s basically invisible unless you have bright indoor lighting pointing at it.
Can I remove and reapply the film without damaging my windows?
Yes, absolutely. That’s the beauty of static cling ā I peeled mine off twice during installation and repositioned it without any residue or damage. The product data says it’s reusable, and I found that to be true. Just make sure the window is clean when you reapply, or the electrostatic grip won’t hold as well.
I found this perfect for renters who want temporary decor without the commitment of permanent adhesive films.
What sizes are available for this film?
The DKTIE Gem Rhombus comes in a bunch of sizes ā I went with the 17.7in x 78.7in, but there are also 11.8in x 78.7in, 23.6in x 78.7in, 29.5in x 78.7in, and 35.4in x 78.7in options, plus longer 118.1in versions if you have a bigger window. That range makes it easy to find something close to your window dimensions before you cut.
How many tools come in the box?
Three installation tools are packed inside the paper tube ā a squeegee, a cutter, and a measuring guide. I was pleasantly surprised by that since most window films I’ve tried require me to hunt down my own tools. The squeegee in particular was solid quality and made bubble removal way easier than using a credit card.
Is this film safe for classroom use?
I think it’s a great option for classrooms, honestly. The vinyl material is durable, the rainbow effect is engaging for kids, and the static cling means you can remove it at the end of the year without leaving marks on school windows. Just keep in mind it doesn’t block visibility, so it’s more about decoration than privacy for a classroom setting.
My Final Verdict
The DKTIE Colorful Gem Rhombus Decorative Window Privacy Film in the 17.7in x 78.7in size has genuinely transformed my plain apartment window into a conversation piece. The UV7 printing delivers vibrant, double-sided color, and the static cling installation was effortless ā I had it up in under 10 minutes with the included tools. I’d recommend it to renters, teachers, and anyone wanting stained glass vibes without permanent commitment. I would not recommend it if you need actual privacy ā it’s decorative, not opaque.
Yes, the rainbow effect fades on cloudy days, and you can still see silhouettes through it. But for the price and the visual payoff, I’d absolutely buy it again. The agate-inspired pattern is stunning in direct sunlight, and knowing I can peel it off and move it to a new window without damage makes it worth every penny.
