This is working extremely well. I am 6'5" and it probably would be better if it went up another 3/4 inch, but I knew it was going to be borderline when I ordered. Anyone taller than 6' 5" this model would probably not do it. There is a slight wobbly at full height - but only if you actually try to wobbly it, But for just working - it stays very still. I did have the top custom sized (54" wide) probably delayed delivery a few days - but it really came pretty quick. Note: it was extremely well packed, absolutely not damage at all. It went together pretty easily, however I did not get the wire management system, I spent a lot of time routing and tieing up all the wires. Came out perfect, the only wire showing is the power supply cord. (Even at full height) I have the one touch programmable height adjustment, could not do without it. I currently run it - sitting for 20 minutes, standing 10 minutes. - so it gets adjusted about 12 times a day. I have associates that have other brands, I am trying to be careful not to rub it in that I have the best one out there. (evil grin)
