SOLID! Been looking for a reliable sturdy bag holder for some time now and was very happy when I found this one, I am sometimes skeptical about buying things like this online without testing it but I read a few reviews and gave it a shot. This lived up to the name and more, extremely sturdy, also, very very easy to assemble (less than 10 minutes) and even move around if needed! I use it for both my heavy bag and my water bag, which are both filled very heavy and i hit with max power (150 lb water bag, filled up to the max) and my heavy bag filled with 80% sand which is about 150 lb also. Holds both with no issue, no sqeeks or not even a wobble. I like having the adjustable height, I usually keep it at or around max height and it is still 100% sturdy, but it's great how height is interchangeable in less than 10 seconds. Definitely extremely happy with my purchase, for such a affordable price
