I purchased this item on 2020 Thanksgiving deal, so far it has been working so well. I like the how the control panel is next to the seat, you know, we have too many controllers in the house. Everything is straightforward to use. I thought I would hire a plumber to install the item but when I opened the product all the instructions, tubes, valves are so easy to use. I contacted the company's customer service email once when I was installing the product, they are very helpful in providing solutions, and the response time is so fast even during the holiday season. I highly recommend the product, it is a life changer.
