Customer’s Reviews

Customer AVery good. Easy to install!
Great idea. My son’s boarding house doesn’t have a washlet, so I installed this one. It can be easily transformed into a simple washlet. My son was very happy with it.
-
Customer IAmazing!
I gave up on the washlet because the toilet doesn’t have a power supply. There were other overseas products, but I was looking for something made in Japan and I came across this. It’s easy to install and highly recommended. 100% satisfaction.

Customer ENo power supply required, no risk of electric leakage
The branch faucet and screws are made of resin and are a little long and interfered with the wall, so I’m worried about the durability, but the installation is easy and comfortable to use.
