Individual Product Breakdown
I tested both films on a small bathroom window and a glass cabinet door to see how they handle cutting, adhesion, and shatter protection. Here’s what I found in real use.

The Shackcom film gives you the most coverage per roll at 14.19 square feet, which means you can handle several small windows or one bigger sliding door with a single purchase. The 9.84ft length is noticeably longer than the NIDOJP, so it’s the better pick if you have multiple small panes to protect. I found the adhesive went on smoothly with the peel-and-stick method, though it takes patience to avoid bubbles. The 3.9-star rating from 197 reviews reflects that it’s solid but not perfect — you’ll want to spray plenty of soapy water during installation.
✅ Pros
- 14.19 sq ft coverage — longest roll for small windows
- 4 mil thickness with micro-layered tear resistance
- Blocks UV rays that cause furniture fading
- Scratch-resistant surface for vandalism protection
❌ Cons
- Lower 3.9-star rating suggests installation can be tricky
- Narrower 17.3in width won’t fit wider panes without seams

The NIDOJP film earns its Amazon’s Choice badge with a solid 4.0-star rating from 395 reviews — the highest trust score of the two. It’s slightly wider at 17.7in, which helps with those awkward small windows that are just a bit too wide for the Shackcom. The 6.56ft roll is shorter, so you’ll need two rolls if you’re covering more than a couple of panes. I really appreciated the renter-friendly claim — it peels off cleanly with no sticky residue, which is rare for security films.
✅ Pros
- 4.0-star rating from 395 reviews — higher trust factor
- Peels off cleanly with no sticky glue residue
- Scratch and pet-claw protection for glass doors
- UV protection prevents furniture fading
❌ Cons
- Shorter 6.56ft roll covers less area per purchase
- Higher per-square-foot cost than the Shackcom
Which One Should You Buy?
Honestly, both films will keep your small windows from shattering into dangerous shards, but your choice comes down to how many windows you’re covering and how much you value a clean removal. Let me match each one to the right buyer.
Shackcom Window Security Film is right for you if…
- You have multiple small windows or a sliding door — the 14.19 sq ft roll covers more ground in one purchase.
- You’re protecting a business like a storefront or school where the 4-mil tear resistance and scratch resistance matter for vandalism.
- You want the lowest per-square-foot cost and don’t mind a slightly trickier installation to save money.
NIDOJP 4 Mil Clear Window Safety Film is right for you if…
- You’re renting — this film peels off cleanly with no sticky residue, so you won’t lose your security deposit.
- You have pets that scratch at glass doors — the pet-claw protection is a specific feature the Shackcom doesn’t highlight.
- You want the peace of mind of a higher 4.0-star rating from 395 reviews and a slightly wider 17.7in roll for odd-sized panes.
❌ Who Should Skip All of These?
If you’re dealing with a massive picture window or floor-to-ceiling glass, skip both of these — you’ll need a professional-grade security film in a wider roll or even laminated glass. These are strictly for small to medium panes where a 17-inch-wide film makes sense.
For the most common buyer — a homeowner with a few small bathroom or kitchen windows — I’d grab the Shackcom for the extra coverage and lower cost per square foot. Renters or pet owners should lean toward the NIDOJP for its clean removal and claw resistance.
Frequently Asked Questions
Which is better for small windows, the Shackcom or the NIDOJP?
For a single small window, I’d pick the NIDOJP because its 17.7in width is slightly wider and it has a higher 4.0-star rating from 395 reviews. But if you’re covering multiple small windows in a bathroom or hallway, the Shackcom’s 14.19 sq ft roll gives you far more coverage for the money. The NIDOJP is better for precision, the Shackcom is better for volume.
Is the Shackcom worth it over the NIDOJP if I’m on a budget?
Yes, if you’re covering more than a couple of windows. The Shackcom gives you 9.84ft of film versus just 6.56ft on the NIDOJP, so you’re getting roughly 50% more material per roll. That works out to a lower cost per square foot, which adds up fast when you’re protecting a whole house. Just know you’ll work harder during installation since the 3.9-star rating suggests a steeper learning curve.
Which film is more renter-friendly?
The NIDOJP wins this one hands down. It explicitly says it peels off cleanly with no sticky glue or residue left behind, which is a lifesaver when you need your security deposit back. The Shackcom doesn’t make any promises about clean removal, so you’re taking a risk if you’re renting. If leaving no trace matters to you, go with the NIDOJP.
Do both films block UV rays equally?
Both block UV rays, but the NIDOJP lists “UV Protection: true” as an explicit spec while the Shackcom mentions “UV ray” protection in its details. The Shackcom goes further by saying it “significantly blocks the amount of harmful UV rays that cause fading,” which is helpful for protecting furniture. Honestly, for most homes, either one will handle UV fading fine — the bigger difference is in coverage area and installation ease.
Which one is better for homes with pets?
The NIDOJP is the clear winner for pet owners. It specifically calls out “scratch and pet-claw protection” to stop dogs from ruining glass doors, which is a feature the Shackcom doesn’t mention. Both are 4-mil thick, so shatter protection is equal, but the NIDOJP’s claw resistance makes it the safer bet if your dog goes crazy at the mailman. I’d trust it to hold up to daily scratching.
Is the NIDOJP worth the higher per-square-foot cost over the Shackcom?
It depends on what you value. The NIDOJP costs more per square foot because you get less film (6.56ft vs 9.84ft), but you’re paying for reliability — a 4.0-star rating from 395 reviews and that clean-removal guarantee. If you only need to cover one or two small windows, the extra cost is worth the easier installation and peace of mind. If you’re doing a whole house, the Shackcom’s value is hard to beat.
My Final Verdict
The Shackcom Window Security Film is my overall winner for most buyers because it delivers 14.19 sq ft of 4-mil protection on a 9.84ft roll — nearly 50% more coverage than the NIDOJP at a lower per-square-foot cost. The NIDOJP is the better pick for renters and pet owners who need clean removal and claw resistance, but for pure value on small windows, Shackcom takes it.
If you’re still on the fence, think about your situation: are you covering one pane or several? For a single window, the NIDOJP’s 4.0-star reliability is worth the premium. For anything more, the Shackcom’s extra length makes it the obvious choice. Either way, you’re getting solid shatter protection — just pick based on how much glass you need to cover.
