I switched to this from the smart bidet seat by Panasonic. The all in one smart toilet can have more useful functions, such as auto flushing, sensing flushing. And it’s Beautiful!! The functions are just what I needed. Installation is easy. The price is extremely competitive. I have check the internal, it’s the same high quality as those brands costing much more. Should be able to last long years. I will replace my other old toilets with DeerValley. Wayfair is great too.
