I had previously purchased a Korean bidet toilet seat, and decided to try a Bio Bidet for the second toilet. The Korean bidet does look a little sleeker, as it has an instantaneous water heater rather than a tank. However, after a couple of years that heater no longer works! The Bio Bidet performs very well, and is much better value for money. I also like the standard braided water hose that it uses. My order was despatched the same day and arrived very quickly.
