They do what they are designed to do However, one of the internal parts of one of the legs that helps it attach to the top was missing. I have a top fully assembled and configured; the other has three sturdy legs and one wobbly one, I hope it stays balanced so the monitor doesn't crash. I wrote to the company/seller - no answer. Not impressed with the lack of response. Otherwise, if you get all your parts to the beat the way they should be, they'll work. If not please let me know if you are lucky enough to contact the company. Thank you!
