We've had this hot tub for one year. I wanted to wait to use this tub for a while before reviewing. Overall I'd say this is a 5-star tub. One issue I had was a couple months ago the top controller stopped working. It was still under warranty and Aquarest spa customer service was super easy to deal with. They sent out a new controller and I installed it myself. The tub material is a little rough and it got rougher after a little use. During the first water change, I used sandpaper to smooth the inside and it worked like a charm. Other then those two issues, this tub has been awesome. I highly recommend this hot tub!!
