A little cooled by the negative comments, I all the same decide to test the thing. And it's really handy !! I have a tub that seems to lend the game with a classical background. The goal being to wet a little the two suction cups beforehand to fold the suction plate to the outside of the party to perform, to position of symmetrical way, and presto, you press a little but not too much otherwise it made folds on the bottom and the water passes through. I spilled water through the shower and I adjusted if there are small leaks (sometimes under a bit). Of course once small in, the barrier will not withstand the kicks or other heckling rather barbaric ... but to play tranquillou no problem! As soon journaliere use since 1 year, I am delighted to decrease my water bill for the bath !!! therefore produces very effective but have the helping hand and a bath without embellishment at the bottom if the board will struggle to position themselves.
