I am conquered by this gear! In general, you must take the gear in the toilet bowl, he moves, not very stable ... This is not the case here. It arises directly from the bowl lowered, and thanks to a wheel adjusts stack the toilet, providing good grip and reassuring my kitties who are literally fighting for its use. The cove is convenient for Loter, transport and wash it without putting too hands. I regret only that it still stretches the height of the toilet. This must be added a footstool ideally for the children to fend for themselves. In a word, great!
