Well designed and sturdy! Assembly was very straightforward. It comes with tools for assembly but I used my own 17mm socket/ratchet and wrench instead as the included tools are not big enough to give you good leverage.
For the most part, It holds my bumpers and bars very well. It does not feel like the tree will topple over with imbalanced weight distributions. However, if you have 45 lb bumpers (or larger), it'll fit 3 bumpers on a collar but you won't be able to put a clip on to secure it (see pic). This isn't a big deal but it would be nice if the collars were a bit longer. I don't think this will be an issue with 3 steel plates.
The barbell holders have a plastic insert that (I assume) is designed to not let your barbell sleeve's get scratched from the metal stand. I found that this plastic insert kept coming out with barbell removal. So I alleviated this with some duct tape (see pic). This is the only negative I have experienced (so far).
