We have had it for 6 months with only one minor problem. The minor problem is that the snap off corners of the outside of the tub come off very easily. If you brush it when you walk by, it pops off. But it snaps back on just fine. We had a Maxxus. The corners were screwed on. My wife is 5ft 4in, and the Maxxus was always too deep for her to sit in. She loves the Kingston. At 6ft 2in, I find the Kinston to be a little shallow.
