Excellent for holding in substrate in a controlled aspect! Makes it so much easier when cleaning out the enclosure to replace with fresh new substrate! Highly recommend!!

This felt very overpriced for it's purpose and actual functionality. It also gave off a pretty strong odor I had to let dissipate before continuing with the build. I used the provided tape, but had trouble getting it to stick once I began adding substrate in. I have to be careful when watering plants or spraying for humidity near the edges. Since the tape did not keep it flush it's easy for me to get some water between the plastic and the PVC wall which then leaks down below the stand and into the carpet. This was only a real issue the first watering or two, after I figured the distance I need to keep I haven't had that problem since. I feel like for the price this shouldn't be something that is an issue though.

Not sure how it works out for the 2' cube, but for the 2'x2'x4' it really needs to be about twice as tall to match the bar on top of the substrate barrier they give you for the enclosure. Being shorter than that, it makes it hard to keep it even and form a good seal near the front and especially near corners, even with the crazy strong adhesive tape.

Might be okay for the 2'x2'x2' cube but for the 2'x2'x4' it leaves nearly half the substrate barrier uncovered and makes it somewhat prone to leaks in the corners where it's hard to get a good seal.
