These security blankets are great! You get a whole lot for just a small amount, they're very well made and durable! I bought this 20 pack because I'm trying to keep my tropical plants alive with my new bulbs over the winter (we'll see how it goes) and I needed to set up a grow tent without spending a hundred dollars or more on one Bracket. So I took the route that works best for my budget and bought these comforters. My "tent" is a little big as I need to accommodate a lot of plants, but I still only used about 5 blankets, the length is perfect as it goes from the top of the basement ceiling to the ground. . And they are sturdy, I used masking tape to tape one "wall" of ceiling to another and for the "door" I put a piece of tape on and just peel it off when I need to get in. The 'door' blanket has not yet stretched or torn due to constant unwinding, very well made blankets! The add-ons will probably go in my car for the winter, you get so many it's easy to gift people. if needed.
