6 Mil Mylar Film Roll, 4 ft. x 25 ft. Diamond Film Foil Roll, Heavy-Duty Reflective Film for Grow Tent, Warm House, and Grow Room (25 ft.)

Not sure what other people bought but this is definitely 6 mil, very heavy, nice pattern. You do have to be a bit careful, as with any plastic film. If you fold it over an object, it will crease or mark. Was concerned how to mount but I just stapled it to a stick and it certainly looks like it will hold up well. Keeps light in my hydroponics setup. Recommended.

Great product and I have no complaints as far as the quality of the product itself. My only complaint is that I have been shorted a foot in each of the two rolls that I’ve ordered! If you are looking for exact footage I’d suggest ordering a size up. Unfortunately, I did not measure the par intensity before and after using the DM but I have noticed a significant difference in overall lighting and plant growth.

Nice and fairly heavy works good worth the price

Very good reflector in the market. Not only it is durable product which does not tear easily, but also easy to cut into sizes using scissor or box cutter. This make my job a lot easier. The delivery is pretty fast and on time. Overall it is a good quality product for the price. You can get better deal if you buy a longer role.

I wanted something a bit more durable than the thin flimsy Mylar I used for my last garden. This material is thick, durable, and has worked exactly as I had hoped. I used a grommet tool to set ring grommets at the top edge of my reflective curtain, and used zip ties and magnets to secure the curtains to the metal lettuce racks. Thick, durable, highly reflective, and a nice clean/neutral white on the outside. My only gripe - the end cuts were not perfectly square, but they gave me a bit of extra length so I was able to cut the roll ends square and still have a bit over 25’. I would buy this again with no hesitations if I expand my winter garden further.
