Bio Bidet A8 Serenity Elongated Seat

Second edit: the seat warmer has ceased to work, after just two years of ownership. My last bidet, a coway, lasted 7 years. Edit: after using this bidet for several weeks now, I've gotten used to the softer spray. One advantage to it is that it doesn't splash water everywhere, so there's less to mop up with toilet paper prior to starting the dry cycle. I've gotten used to the way it works, so I'm changing my review from 1 star to 3 stars. It's ok. It's not bad. I still am not happy about the fact that I can't use Eco mode and still have the seat warmer on. I left my original review unedited below, for those who are curious about why I initially hated it so much. TL;DR: Keep looking if you want a bidet that has a strong spray and good oscillation/massage features. This one is completely inadequate in those regards. A bit of background first: I owned a Coway BA13 for almost 9 years, and loved it. Eventually, though, the rear spray nozzle stopped working correctly, and the seat sensor decided to work intermittently as well, so I figured it was time to get a new bidet seat. After some research, I bought a Brondell Swash 1400, which scalded me with incredibly hot water, so I exchanged it for another. The second one arrived broken -- the seat sensor didn't work at all, so it wouldn't go into Eco mode, and wouldn't stop spraying/drying when one would stand up. QA is clearly not their strong suit, so I decided to try BioBidet. I'm trying to steer away from Toto because as a user, I've found the strength of the spray on Toto bidets to leave much to be desired. BioBidet, according to some internet research, has the highest GPM of the three brands, so I thought it would be at least as strong as the spray on the Coway or the Brondell. Nope. Not even close. 1. The spray is so weak, I feel like I have to spend more time just to be sure everything is taken care of. It definitely does not do its job expediently. 2. The Eco mode is dumb -- the seat warmer turns off in Eco mode, so you end up sitting on a cold toilet seat. Having a warm seat is one of the joys of these bidet seats, so I had to turn off Eco mode. Lame. 3. The dryer, on its hottest setting, almost burned both me and my bf on our bums, on the left side (I'm guessing, although haven't verified, that the dryer is on the left side). We had to turn down the dryer to a lower setting, so it's obviously less effective (although dryers on these things are never that effective -- I always use TP first to do an initial pass, especially since this one has to use so much water to get the job done). 4. The massage and oscillating functions are utterly and completely useless. I used to use an oscillating feature on the Coway and Brondell bidets, but on this one it just seems to turn off and on -- not move back and forth or side to side or anything. 5. The unit doesn't save the last used water temperature, for some strange reason. It keeps going back up to 39C, which is way too hot for female parts. I need to try to set up user settings to see if I can get it to stop doing that. 6. The remote control is ridiculously unintuitive at first, and overcomplicated by the fact that you have to turn it over to make adjustments. The Coway/Brondell remote does all the same things with a much more elegant interface. I haven't decided if I am going to return this unit yet. If this is how it's supposed to behave, then I'd have to find yet another brand/model that might be better. Too bad Brondell sucks so much -- it really did work just like my Coway did, except for the scalding hot water and other quality issues.
