I only use two presets, which is just fine since I mostly stand now with my balance board under my feet.  I like the clean look and feel of the desk and it was easy to assemble. I recommended to my cousin who also bought one. So far it does the job. I am lucky to be able to WFH during this pandemic and to be able to purchase something that is better for my health than sitting all day. It's great to be able to stand up and take calls .
