Very smooth roller. Folding guides are a good idea and useful when working with some narrow materials. It's very light, I think too light because it tips over very easily. The height mechanism is very smooth and works well. One of the main issues is the lack of a lock to keep the legs in the unfolded position. This means if you lift it incorrectly, your fingers will be crushed when the board swing closes and you'll have a hard time just sliding through the workshop because the legs keep wanting to fold. I'll probably add a locking arch, but it would be nice if it was part of the original build.
