This standing desk converter seems to be well worth the money. Two big pluses to others that I considered are the cost (less than $100) and the fact that it comes fully assembled. It seems to be well-made with high quality materials and is very stable in any of the raised positions, even with a large monitor on top. Once you have it where you want it, it stays put. The surface is large enough to accommodate the monitor, a keyboard and even a laptop when I need to use it for a second monitor. My only gripe is that it is, initially, a bit hard to raise it; the pneumatic assist doesn't seem to kick in right away so you are lifting the full weight at the beginning. When the assist does kick in everything is very smooth. Considering the cost and quality of this unit that's something I can easily live with.
