It's been 6 months and I still love my Hamilton. We had a minor problem with a light(came on for no reasom) but the dealer quickly fixed it and everything has been great. We have the ozonator, and the filter seems to be keeping everything spotless. As I said in an earlier post, I didn't really like the lounge when we wet tested, but my kids insisted on a lounge, and it has become my favorite spot in the tub. The only thing I don't like)and this is very minor) is the difficulty getting the panel door back on. It seems Sundance could have come up with a better set-up, but this is my first hot tub, so maybe all panels are tough. Hopefully, I won't be taking it off very often.
