Standing Desk Frame Dual Motor- 3 Tier Standing Desk Legs, Adjustable Desk Frame, Sit Stand Desk Frame，White Frame

I generally don't write reviews, but I'm extremely disappointed that the motors will only move the desk with roughly 330 lbs of weight about half an inch at a time when pressing the up arrow. I removed about 40 lbs. and it still struggled, stopping after about 6-9 inches of travel. Had the press up arrow dozens of times to get it move to the highest point I wanted, set the number, ran it to lowest setting, but when pressing the number to take it to high point, when loaded, it again only moved about a half inch.Update - 07/28/2024:The company reached out to me offering a full refund, but also included some instructions. I didn't even think about a break-in period. After removing the primary glass top and the two drawers, and running the desk up and down at least two dozen times over three days, I set the 'sensitivity of anti-collision' to (0) - was (1) - and put the glass top back on. Surprisingly, it worked. The motors seems to be working a little harder, but the desk moved freely all the way to the upper set position without stopping, at a decent speed. I then added the two drawers and water bottle, and a few things that I would normally have on the desk. This time the motors struggled hard and it took longer, but the desk made it all the way to the top without stopping. I cycled it several times, and the desk made it to the top although the motors were struggling a lot. By lifting on the glass a little, taking a bit of weight off, the motors ran at decent speed and lifted the table quickly.I'm satisfied with the motorized legs, with a bit of break-in, are able to handle the weight of a 72"x30" butcher-block wood top (70 lbs.), my favorite glass desk top (70+ lbs.), 4 monitors and all the supports, and a couple of laptops and external drives, and the two drawers with misc. stuff. By lifting on the glass top, the motors run well, struggle less, and move relatively fast.I'd like to find out if the one controller could be used with a splitter to control two sets of motorized supports, (4) all together, and I'll mount the other two on the back bar, at least a foot in from the ends. Then I wouldn't have to lift on the glass, I think 4 legs should be able to handle the weight distribution efficiently, without assistance.
