I tried all the brushes, picks-stuff .... and as I have a kitchen table with tiles with recessed joints, it does its job, and that's what I found most effective . Moreover chosen based on the reviews of other buyers, on which I base many of my purchases. They are always helpful and expected. It's funny, discreet, friendly, easy to use (even if it takes a little searching the buttons to open it) and especially swallows everything! Batteries ?? I always use rechargeable, so no worries! Amazon delivery perfect, as always!
