I installed this last month and has worked great. This was a birthday gift for my lovely bride, she had wanted one since seeing a TOTO version in Japan about 10 years ago. The unit looks well made and comes well packaged. There are a few things you should know. FIRST, this seat is designed for an elongated toilet bowl. The round bowl style would probably not work. Since we had the round style, I did replace the toilet with a modern low flow toilet. (needed to do that anyway, old toilet was a 5 gallon/flush unit from days of old). I also used this opportunity to replace the water shut off to the toilet, the old shut off started leaking as soon as I tried to turn it off. SECOND, you need a 115 volt, 15 amp electrical supply (very) near the toilet. This can be a big deal. I got lucky and was able to easily install a new outlet right behind the toilet. I gave it a new dedicated 15 amp circuit.(This step is way easier to do this once the old toilet was removed and out of the way)With the new water shut off, toilet and outlet installed, placing the new seat and hooking it up were almost trivial. Connect the water supply to existing lines, bolt the seat down, plug it in. That's it! My wife is very please with the function.In short, if you have a modern elongated bowl toilet, with a working shut off and a nearby outlet, you can install this thing in 15 minutes, easy. And you will be happy with the new seat, the features are great and the remote is easy to use. The biggest deal to contend with is the site prep PRIOR to installation, this may be beyond most homeowner's capabilities. In that case you will need both an electrician and a plumber and the bill can rack up pretty fast.
