This is a better product than the previous Bio bidet that I had that cost twice as much and I used it for 5 years without a problem, at half the price!
There were only two glitches I experienced:
1. Amazon sent me a previously returned unit that looked like it had been in a flood. It still had the return sticker on it to the Amazon returns center! My guess is that the previous customer told Amazon it was OK, but it was DOA when I installed it. The good news was that I was't able to order an identical replacement, so I just got a credit and when I went to order it again, the price had dropped about $60!
2. I didn't look closely at the install instructions and tried to install the T fitting provided at the valve instead of the underside of the toilet. Bio bidet technical support straightened me out politely (they must have had a good laugh!)
It was on sale for a ridiculous price for about $170 something.
It's great. The only feature lacking is a heated dry cycle which I never used.

With this ongoing Amazon discount, and after reading all the reviews I just could not resist. After 2 weeks of daily use, I am overall pretty satisfied with the product's build and ease of use. I would've definitely gotten a TOTO a few years ago but it's out of my price range, so the Slim Two is perfect in its affordability and high quality.

Pros:

- Easy installation
- Great sturdy build, especially the heated seat; no creaking/squeaky noises at all
- Remote control (I was initially going for the Slim One (without remote), but the Slim Two (with remote) was less expensive and it's also very nice to not have to twist around to reach the console on non-wireless models); also, the remote comes with a wall mounted dock which you can stick onto the wall with the included adhesive (included) or use screws (not included).
- Pressure options and nozzle positioning is perfect -- I don't understand why some users have reported problems. Perhaps your hose connection is not secure or the emitter is blocked? Also, Turbo Mode pressure is TOO strong -- I still haven't found the need to use this mode. It's so strong that it causes spray-back and leaves the back of the seat with water beads.
- Nightlight (though turning it off is not intuitive at all (the "+" button requires a long press of 3 seconds). The nightlight should be light sensitive, triggered by a proximity sensor or simply redesign the remote to include a dedicated nightlight button).
- The water heater works great; lasts more than 60 seconds. The water is not scalding hot, but hot enough for a thorough cleanse. IMO, 30-60 seconds is optimal for a thorough cleanse unless you have a really wide area to work on in which case you double press "wash" to activate oscillation for a wide clean.
- Easy installation guide (everyone writes that no guide or manual is included -- my order came with two manuals: a regular installation guide and a quick start guide).
- Toilet paper use and expenditure is cut in half. Only need a small bit for dabbing excess water. Very nice!

Cons:

- I needed to purchase a hose reducer to fit the hose nut over the water connection. It was under $5 at Home Depot.
- The nightlight could be easier to turn on/off (see above).
- The remote interface design is NOT good -- I think BioBidet could take some design cues from TOTO or INAX on good UI design for their remote and also make one universal remote for all their similarly featured models
- When I opened the box and pulled the seat out, residual water dribbled out the hose and unit and spilled all over me which was odd because it is a new, unrefurbished model (or is it?) Very strange -- but the unit looks and smells brand new at least so I'm not overly concerned.
- I know this is beside the point, but the BioBidet logo needs a total brand overhaul. The typeface used in the words "Bidet" looks like it can't breathe and is squished together, while the "Bio" typeface is relaxed and well-spaced. Consistency will reposition the brand to reflect the brand's high quality products.

Overall: At the sale price of $189, I think EVERYONE should have one of these. You will feel super clean after seconds of washing. When I lift off the seat, I feel so clean while everyone else is walking around with dirty, poo-smeared butts. Yuck! Go get one now!

Update (October 31, 2018): Now that the weather is cooler, I can understand why the heated seat function is such a helpful feature. It never occurred to me previously just how much temperature affects parts of your body, but now I find that I am more relaxed when the seat is warm and can finish my business faster. It's like when you jump into the cold ocean and everything clams up , the same is true when you sit on an ice cold toilet seat -- it just takes forever to peek out and if you don't get to finish your business, you feel backed up and miserable. In the past, I used to think a warm seat would feel kind of gross (like it was just used by someone) but now that I am more relaxed when I sit down, I just can't go on without this feature. I think it helps you achieve regularity.

Update (September 30, 2018): After 30 days of daily use, I would highly recommend the SLIM TWO. The seat is very high quality in terms of construction and function and you will feel so much CLEANER!

Update (July 1, 2019): BioBidet Customer Service is top notch.

Update (August 12, 2021): The second lid replacement suffered the same fate and the hydraulic right hinge broke again. There is no way to fix it since the plastic bit disintegrates and pulverizes into a hundred pieces. I think BioBidet should find a better material that can withstand the test of frequent opening/closing. Other than the hinge issue (which is not a problem with our Toto), the Slim Two is a great deal. But after reading multiple other reviews citing the same hinge quality issue, I may likely switch to the higher quality Toto C200 which I have in another room and has experienced absolutely no issues.

Overall, this is a nice bidet at a very good price with some caveats.
+ nice looking
+ built-in nightlight
- the seat doesn't line up well on some toilets with a forward curved tank, especially noticeable on toilets with a round bowl
- the lid has a steep angle that precludes its use as a seat, such as where one might sit while giving a toddler a bath
I tried it for a few weeks and have no complaints about its functions. However, the shortened opening makes it awkward for males and some females.

All in all, this is a good product. I benefitted from reading reviews regarding installation. It helped me avoid mistakes and be patient with the process, which took me about an hour. For those wondering about the rubber nuts that have to squeeze through the attachment hole in the toilet - I found that VERY GENTLE pressure with a non-scratch tool (I used a hard plastic child's screw driver) on one side, while pushing with your hand on the other side, allowed the bump to slide down pretty easily. The seat is very soft and comfortable. I am glad for the option of turning off the night light, and the seat heater. My one disappointment is that the remote is completely smooth and not backlit. So, in the dark, one is left guessing about where the correct button would be. I can see that maybe from a cleaning standpoint, this is easier to wipe clean. But, not very practical otherwise. Anyone who has used the BioBidet toilet attachment will notice that the water pressure in this unit is much less, but enough. I would recommend this item.

Installation would have been easier if the instructions had shown how to install the rubber anchors, although the unit can be installed without them. I had to squeeze the hollow rubber ball in the anchors and fold it on itself to be able to get it through the hole, and this I had to figure out on my own. Other people have written reviews saying that they could not get the anchors installed at all, which is a shame because they make the rest of the installation easier.

I also wasn't exactly sure how far back on the toilet to place the mounting plate (there are zero clues for this), and so I had to take the seat off from where I first placed it and move the mounting plate back one notch. I probably should have moved it two notches, but it is extremely difficult to get the seat back onto the mounting plate, and I never want to have to do that again. There are no guides to show you where to place the seat in order for it to fit onto the mounting plate, and so you just have to get lucky. It was worse the second time because it had water in it.

Once it got installed, it was great to use. The water was very warm, even on the medium setting, and the pressure is adjustable, which is very nice. The massage setting is useless, however, but that is not important. The jet does a good job of cleaning (the primary function for this), but the fan for the dryer is too weak to be effective. I decided to hang a hair dryer on the way next to the toilet, and that can take the place of toilet paper.

It is necessary to keep the instructions page (which can be attached to a wall with a suction cup) for the remote control handy, as the icons are not always intuitive. I would never know what some of the buttons on the remote control do without the guide.

I'm overall happy with the product - not happy with the difficult installation.
