This item is trash. First of all, there is a problem with the craftsmanship. The holes for the screws are not properly aligned in all places, so it takes a lot of effort to put this together tightly. Secondly, this product cranks down just fine, but it is problematic to crank up. I literally have to sit on the floor and use both hands and a lot of effort to position it to standing height. I want to return this garbage item, but there's a $185 fee to do so. Save yourself some time and headache. Do not buy this garbage desk.
