Question: Is this seat elongated?
Document: After living in Asia, I really loved having a bidet. After moving back to the US, so hard to find where to buy them. Heated seat, heated water, easy to install & easy to maintain. Not too expensive.
How do you feel about a cold toilet seat? Or when you do your business and then it takes wayyyy too much toilet paper to get the nooks and crannies all wiped down?This bidet solves all that! I went on vacation in Korea and got a taste for the super fresh feeling you only get from a bidet. My ordinary American toilet with a cold seat and no Bellagio show was no longer enough.It's easy to install.
My first unit was HI2000, about 8-10 years old. Need a replacement incase the HI2000 fails in my senior mother's bathroom (had a reset for unknown reason and time). Hometech has a service and parts department  that got me replacement parts knowledgeably and quickly when I misplaced the seat attachment assembly. Had to replace a round seat with a long seat when I did an upgrade toilet; It was an easy replacement with detailed printed and online video instructions.
This product lives up to its name. Everyone in our home loves it, and we have recommended it to our friends.
The water supply is a t-valve you hook onto the bottom of your toilet tank. Easy peasy. It has push button settings to adjust spray and heat (aim is adjusted by wiggling the nozzle itself, somewhat a guessing game)The biggest down side - this model doesn't have a dryer. If I had a time machine and could do it all over again, I'd probably opt for one model up with the dryer, but as cheap as this was it was worth it.
I have tried other brands but found their service to be very poor but the product pretty good. Recommend that you purchase with good service.
Basically the pressure sensor which is supposed to switch on/off the heat units, does not work in my unit. Therefore, I manually switch both heaters as required. Other than that, unit is functional. The spray quality is single jet and not a spread spray. So mind the pressure settings.
An auto-off feature would be nice, but really that's a first world problem, no?
Answer: yes
