I love the ability to roll this around and to be able to use it in different ways, and I can’t complain at this price point. The instructions and the labeling of the pieces could have been better because the pieces look similar, which made me question whether I was putting it together correctly. It don’t think it is meant to be adjusted up and down often, otherwise I may expect it to loosen over time. For example, I used it as a standing desk for my laptop, and the table will slowly slip down, so I have to really tighten it.
