Altus 2 层站立式办公桌 高度可调 电动坐立式办公桌

I love my desk when it works but I use the whole desk and often brush up against the controller so the desk moves or goes into error because it is at the front edge. It would be better mounted at the second tier. I will be moving mine. I kept the instructions but the error codes aren't listed and the functions don't always work
