Flimsy. Everything is held together with gravity, so if you move it whatever you grab will come off. This would be acceptable but the stand itself was bent and/or misaligned so that it rocked quite a bit when complete. I had to put a coaster under one of the legs, which seemed short by at least a quarter of an inch. Only worth it if you absolutely need this particular solution, i.e. needing to hold two 30 gallon tanks one above the other.

It fits my aquariums perfectly. I love it. Plus it don't look bad in my home.

I bought the largest stand to hold my 55L tank. The stand is a bit deeper than my tank, but the length is exactly the same. I wish there was a lip or something for a little extra security. That said, my tank has been jumped on by a couple of cats with no issues. I don’t think it’s going anywhere.

Came as described. Seems lighter than I would expect to hold the amount of water it’s supposed to but I only use 15 gallons in my 40 gallon tank. Works for me.
