This VIVOSUN Mylar film is fantastic! I was a little worried about the thickness, but it's perfect—not too flimsy, but still thick enough that it feels durable and won't rip easily. Cutting it to shape was a breeze, which made my little project so much easier. I'm using it to grow some cactus seeds and it's working great. The reflective material does an amazing job of bouncing light back onto the seedlings, and it definitely helps with heat retention. The best part, though, is that you can see through it just enough to check on everything without having to take it down. Plus, it's a great way to keep my nosy neighbors from thinking I'm running some kind of illegal grow operation instead of just pursuing my hobby! Highly recommend it.

The product quality seems excellent, though I have not unrolled the entire roll for inspection. The only problem I encountered was some shipping damage. The first 20 feet or so were damaged (about the lower 4 inches) because the box it was shipped in was 52 1/2" long. This is one of those "Ahem, attention Amazon..." reviews. This was a 4' long roll. That's 48". It was wrapped in plastic, so as a shipper making boxes I'm allowing between 1/2" and 1" max for the wrap. So a 48 1/2" to a 49" box. IF you ship it in a box at all (a shipping tube is preferable for rolled damageable items, and easier to size). NOT a 52 1/2" box. Know what happens to a tight roll of something if you give it a chance to slide back and forth 4 or 5 inches? It tends to be a not-tightly rolled up roll and it will walk off the roll to one end. Which is what happened. And a good chunk of it was crinkled and damaged as a result. Now yes it's an amazon shipping issue, but...I received damaged product. So took off a star, which seems fair. Was it bad enough to send it back? In my opinion, the amount that was damaged didn't warrant the effort that would have been required. So...meh. So if you order this, you might want to add some special instructions to the order and request they package it carefully and without much end play. Now, the product itself, once I got past the damaged section, is great. The coating is smooth, reflective, and even, and, for 2 mil mylar, is pretty durable. If they can get Amazon on the ball, shipping-wise (honestly, it's a problem their shipping department can solve with a 10 minute training session on shipping these types of items) this is a 5-star product. Very high quality and I would absolutely recommend it.

Great material if you are looking for a durable metallic film. I bought it to make a photo booth for my child’s Bat Mitzvah and it worked amazing!!! . Does not tear apart like the space blankets, it can be wrinkled without being messy and the price is reasonable for 100 feel! Highly recommend

*****Update******: VIVOSUN Customer Service reached out to me and sent a replacement roll right away. They informed me that the first roll was a manufacturing defect. I am very pleased with this new mylar film roll. I am even more pleased in the level of service I received from VIVOSUN. I plan to continue purchasing from them whenever possible, knowing they stand behind their products. Well done! ________________________________________ (Previous Review): I am pretty happy with this Mylar film. Didn't experience any streaking, but I did notice that it is easy to create streaking/scratches if you are not careful. You will want to take care to unroll the film on a clean smooth surface; any abrasion may leave streaks/scratches easily. It is pretty thin (only 2 mil. thick), but it is surprisingly durable. I used a staple gun to hang some sheets. Even after some serious tugging/pulling, even stepping on the bottom, the film didn't tear or come loose -- there was some streaking/scratcges though with minimal contact. This film is not forgiving when it comes to scratches. I will say it is very reflective. Although, It is translucent. You can clearly see what is on the other-side, when looking into a lit room, from a dark room. It is comparable to some serious limo tint. 1 layer thick and it block almost all the light from coming through. But again, it is possible to see through it. This film is also very rigged. It doesn't fold well, it wants to retain its original shape -- but it does wrinkle without too much difficulty. Makes it a little difficult to double up. Honestly, not much light penetrates using a single layer though. This film would be much better with a black poly backing. I would recommend this to a friend as a cheap option for Mylar film. However, I would heavily suggest substituting the 7 mil version instead.

I feel the biggest thing yo know about this product befor purchase is that it is transparent until a background is applied. Think of it as more of a tint. I wanted to use in my growroom and as a background for a wall mounted aquarium. Works in the growroom but not as much as a background for aquarium unless it is a room you dont mind people seeing theough to. Still a good product depending on use.
