Pros: Height adjustable (I use the maximum height), Free moving angle adjustment, feels nice on barefeet. Cons: Rocks from side to side/not stable enough, too narrow and forces me to keep my legs unnaturally close together.

Awesome for long hours at my desk

Does what it is meant to do. It is pretty large so check the space on where you plan to use it

Not great, wish you could lock out the pivot

Sturdy construction. Easy to adjust to correct height. Can rock my feet forward and back and the nodules are great for a foot massage.
