This has been working well.  Considering the cost when compared to other adjustable desks, I don't know why anyone would buy anything else.  I did have an issue when putting it together.  The bar that inserts into the motor and turns in order to lift the desk was very difficult to insert and the directions were not very helpful.  I actually watched a video from a different product in order to figure out how to do it, and I thought I wasn't going to be able to do it, when suddenly it fit in.  Maybe I was doing something wrong, but whose to say as the directions were not much of a help.  So, great product for the price, but four stars because of the issue with the instructions.
