I really wished this product worked! Yes, the instructions were vague. The desk I received works as a desk but the adjustable motor does not work. I have rebuilt it again to make sure I did not miss anything but still it does not work. I noticed that one of the legs were unbalanced and every time I try to adjust, the legs shift up and down but never stays up. The other reviews were great it is just too bad that my product was defective!
