I like this unit I purchased, but I think I need to get a weight to put in the bottom of the extra roll container to stabilize the unit.  It does not wobble a lot, don't get me wrong -- just a little.  So it could use a ballast, which I guess would have made it heavy to produce and ship.  I like that the dispenser is just the perfect size for the narrower tp rolls of today, and it is easy to just  put a roll on.  I do love the tray on top for glasses, phone etc.!
