Input: Inferior product worth only half the $40 price! I knew i was in trouble when i lifted a very lightweight box. Opening it confirmed my suspicion. The provided flip blade screwdriver was not notched for Phillips (it was just a pointed rod), not that it would have been the right size in the first place. The pass-through screw holes on the legs are much too large (the directions indicate that there was a previous product from which this was adapted). There is no bracing and limited spot welding on the leg base. The top is unstable with any weight and vibrates horribly when you type. Honestly, this is the type of Chinese junk we expected 30 yrs ago. The only reason it gets two stars and not returned is that my wife likes how it fits over the side of the bed and will not let me return it.
