Monoprice Sit-Stand Dual-Motor Height Adjustable Table Desk Frame, Electric, Black – Monoprice.com

I never give bad reviews, but…..

….this has been an absolute disaster for me. I usually love MOnoprice, but not this defective piece fo crap from China. DONT GET IT — GOOD IDEA IN THEORY, BUT DOESNT WORK EVEN AFTER A REPLACEMENT UNIT WAS SENT. Controller unit apparently defective and after a replaced control unit, it works erratically if at all. First unit I got had a faulty controller box, simply wouldnt operate legs. Monoprice customer service troubleshot with me, very nice, offered to switch out, but they couldnt just send me a new controller box, had to send me a complete new set with desk legs and all (heavy, big box, huge waste of shipping cost), and I had to remove the controller from the new box, switch out my controller and send it back with the giant box with legs I didnt touch. OK, it worked for another couple of days and then stopped working properly — it would go up 3-4 inches, get an E5 error, go back down an inch or two, then i had to hit the button to get it up another couple of inches, it would get to E5 again and go back down etc. Would take ten or 12 steps like this to get to desired height, and did the same thing with programmed heights too. Real frustrating. tried unpluging, resetting, etc, same issue. But even worse, now it is completely frozen and showing a new error message not even in the instructions r5r. Complete waste of money. Don’t say I didnt warn you…
