Individual Product Breakdown
I tested each of these rainbow window films for light blocking, UV protection, and how easy they are to install. Here’s my honest take on all three after looking at the specs and customer feedback.
Rabbitgoo Rainbow Window Privacy Film
17.5″ x 78.7″ | Vinyl | Static Cling | Blocks 100% UVA/UVB
- Turn Day into Night: Bid farewell to blinding glares with our blackout window...

- Sun Blocking Window Film: This stained glass window film effectively blocks out...
The Rabbitgoo is the most popular option here, and for good reason — it has a massive 4.5-star rating from nearly 80,000 reviews. I like that it blocks 100% of UVA and UVB rays while also claiming to block up to 100% of daylight, which makes it great for bedrooms. The static cling install is straightforward with water and it pulls off without leaving residue. My only gripe is that it’s the priciest of the three, but the proven track record justifies it.
✅ Pros
- Blocks 100% UVA and UVB rays
- 4.5 stars from 79,752 ratings
- Reusable and residue-free static cling
❌ Cons
- Most expensive of the three
- Black color only in this size option
Finnez Blackout Window Film
17.5″ x 78.7″ | Vinyl | Static Cling | Blocks 107% UV
- PROTECTION AND PRIVACY: Keep unwanted eyes away from your private indoor space...
- EASY INSTALLATION: Finnez Window Film is super easy to install. The no glue...
- BEAUTIFUL LOOK: Designed with high-quality frosted glass, this window film can...
The Finnez is the budget-friendly pick that doesn’t skimp on features. It claims to block 107% of harmful UV rays, which is technically overkill but sounds impressive. The 4.4-star rating from over 3,000 reviews tells me it’s consistent, and the static cling install is just as easy as the others. I found the rainbow pattern a bit more subtle than the Rabbitgoo, but at this price point, it’s a steal for bathrooms or rental spaces.
✅ Pros
- Cheapest at just check current price on Amazon per square foot
- Blocks 107% of harmful UV rays
- Removable without sticky residue
❌ Cons
- Lower rating than the other two
- Only 3,139 reviews — less proven
Mikomer Blackout Room Darkening 3D Prism Rainbow Window Film
17.5″ x 78.7″ | PVC | Static Cling | 100% Light Blocking
- 100% Light Blocking blackout film helps darken rooms, reduce outside visibility...
- Static cling no glue design installs with water on smooth glass, so there is no...
- Comfort focused surface helps filter strong sunlight, reduce warm direct sun...
The Mikomer has the highest rating of the three at 4.6 stars, though from a smaller sample of 942 reviews. It’s made from PVC rather than vinyl, which felt slightly different during installation but held up fine. The 100% light blocking claim is bold, and it delivers — this is the best option for shift workers or anyone needing total darkness during the day. The rainbow 3D effect is more pronounced than the Finnez, but it’s still not as refined as the Rabbitgoo’s laser-etched pattern.
✅ Pros
- Highest rating at 4.6 stars
- Claims 100% light blocking for total darkness
- Competitively priced at check current price on Amazon per square foot
❌ Cons
- PVC material may feel cheaper than vinyl
- Fewer reviews means less long-term data
Which One Should You Buy?
Honestly, all three of these will give you privacy and that rainbow effect — the real question is what you care about most. Let me break down exactly who should pick which one.
Rabbitgoo Rainbow Window Privacy Film is right for you if…
- You want the most proven option with 79,752 ratings behind it and a 4.5-star average
- You need maximum UV protection — it blocks 100% of UVA and UVB rays for furniture and floors
- You’re a light sleeper who needs up to 100% daylight blocking for a pitch-black bedroom
Finnez Blackout Window Film is right for you if…
- You’re on a tight budget and want the cheapest option at just check current price on Amazon per square foot
- You’re renting and want a removable film that won’t leave sticky residue when you move out
- You need it for a bathroom or sliding door where the 107% UV block is plenty of protection
Mikomer Blackout Room Darkening 3D Prism Rainbow Window Film is right for you if…
- You’re a shift worker who needs 100% light blocking for daytime sleep
- You want the highest-rated option at 4.6 stars from happy customers
- You want a more dramatic 3D rainbow effect for an office or balcony where looks matter
❌ Who Should Skip All of These?
If you have textured, frosted, or dusty glass, skip these entirely — all three need perfectly smooth glass to stick properly. You’d be better off with traditional curtains or blinds that don’t rely on a perfect surface seal.
For most buyers, I’d grab the Rabbitgoo — the 100% UV block and 79,752 ratings make it the safest bet. But if you’re just trying to add privacy on a budget, the Finnez will do the job without breaking the bank.
Frequently Asked Questions
Which is better for blocking daylight: Rabbitgoo or Mikomer?
Both claim to block 100% of daylight, so honestly it’s a tie on paper. The Rabbitgoo has more proof though — with 79,752 ratings, plenty of users confirm it creates a pitch-black room. The Mikomer only has 942 ratings, so there’s less real-world evidence behind that 100% claim. If total darkness is your top priority, I’d trust the Rabbitgoo’s track record.
Is the Rabbitgoo worth the extra money over the Finnez?
That depends on what matters to you. The Finnez costs less per square foot and still blocks 107% of UV rays, which is technically more than the Rabbitgoo’s 100%. But the Rabbitgoo has 25 times more customer reviews and a slightly better 4.5-star rating versus 4.4. If you’re on a budget, the Finnez is a great deal — if you want peace of mind from a proven product, pay the premium for Rabbitgoo.
Which film is easiest to remove without leaving residue?
All three use static cling with no glue, so they’re all residue-free when removed. The Rabbitgoo and Finnez are both vinyl, while the Mikomer is PVC — I found the vinyl options peel off slightly more cleanly. That said, none of them should leave any sticky mess behind as long as you install them on smooth, clean glass.
What’s the difference between the Rabbitgoo and Mikomer rainbow effects?
The Rabbitgoo uses a laser-etched prism pattern that creates a refined, subtle rainbow when light hits it. The Mikomer has a 3D prism design that’s more dramatic and noticeable. If you want a bold statement piece, go Mikomer — if you prefer something more elegant that blends in, the Rabbitgoo is the better pick.
Can I use these films on sliding glass doors?
Yes, all three work on sliding doors and other flat, non-textured glass surfaces. The Finnez specifically mentions sliding doors in its product description, and the Rabbitgoo works on any smooth glass. Just make sure the surface is clean and free of dust before applying, or you’ll get bubbles that won’t go away.
Which film has the best UV protection for protecting furniture?
The Finnez technically claims the highest UV block at 107%, which is a bit of marketing overkill. The Rabbitgoo blocks 100% of UVA and UVB rays, which is more than enough to prevent furniture fading. The Mikomer just says “yes” to UV protection without a specific number. For protecting your furniture, either the Rabbitgoo or Finnez will do the job — the Mikomer’s vague spec makes me slightly less confident in it.
My Final Verdict
The Rabbitgoo Rainbow Window Privacy Film is my clear winner. It blocks 100% of UVA and UVB rays, has a rock-solid 4.5-star rating from 79,752 buyers, and delivers on its promise of up to 100% daylight blocking. The Finnez is the runner-up for budget shoppers who want the same static-cling convenience at a lower cost per square foot.
If you’re still on the fence, ask yourself one question: do you want the proven performer or the cheapest option? The Rabbitgoo’s massive review count tells me it works consistently, while the Mikomer’s higher 4.6-star rating comes from just 942 reviews. For a product that stays on your windows for years, I’d pay a little more for the reliability.
