This is my second Bona dispenser.  The first worked fine but the bottle design caused a vacuum to build up and would empty properly.  Removal was difficult to refill plus the bottle would be collapsed so you need to blow into it so it would expand before refilling.  not a pleasant task.  The new dispenser  has improved the bottle as is no longer builds a vacuum but it the interior sill collapses and needs to be expanded in order to refill.  The head that holds the mop seems to be backward so the applicator falls off the front when you lift it up.  But I do like the product if I can see a way to combine it with the swiffer dispenser I'll  be on a win win.
