They are fine for anything which doesn’t require precision. I have a Ryobi bench sander and it’s a complete waste of time. Same with the chop saw I unused to have. It was basically impossible to get flush miters from it no matter how much you adjusted it - the tolerances were just too low. My DeWalt table saw and Chop saw don’t have the same issues. They cut sub-mm precision on day one and still do years later. The table saw in particular is technically a worksite saw, buy you can use it to build cabinets with the right blade.
