I am a middle-aged male, quite simple and middle class (I don't typically eat foods I can't pronounce or drive a car I can't afford), and I consider myself hygienic but not OCD when it comes to that. I've never been one for lotions and potions for daily hygiene. I'm a bar of soap and bottle of cheap shampoo kind of guy. This product changed that for the better. If you feel such a device is "weird" or "odd," well if you consider it in an honest way, many of the most interesting and surprising (in a good way) things in life can be weird or odd at first. The device (Neo 120) functions as advertised, for the most part – see below -- and works very, very well. I must say emphatically up front that I did *NOT* receive this item for free or for a discount for my “honest and unbiased review,” nor do I work for the company that makes this device, nor own stock in said company. I have nothing to gain but good karma for relaying my feelings about this so you can make up your own mind: • Installation to the water supply is easy. (If you read ignorant, misleading reviews that claim this device gets its water from the toilet tank (or worse, the bowl), ignore such misinformation). It uses the same water source as the rest of the fresh water in your house, and anyone who actually owns one knows that. When installing the water supply hose to the water feed side and then the bidet, it needs to be tightened snug – not torqued down with a wrench. The latter is totally unnecessary and instead of preventing leaks, it may very well cause them. If you are concerned about leaks, it does come with plumber’s tape—not much, but enough for the job. • As others have said, installation onto the toilet itself can be tricky, especially if your toilet seat dips in the back. Imagine completely removing your toilet seat (both lids), and then placing three stacked quarters next to both holes before putting the seat back on. That is about the elevation that results. DO purchase some cheap white plastic toilet seat hinge bolts that are as long as you can find – 3 inches or so. Those will be needed, and I am surprised this wasn’t issued as formal guidance in the instructions. (If you want nicer bolts, then sure, but no one really sees those. It’s about utility for something like this). This advice is based on my standard toilet. If you have a specialty toilet that normally wouldn’t be a “standard” model in a typical big-box home improvement store, you should investigate further before you buy. • The temperature of the water that comes out of this is precisely the temperature of the cold water that comes out of your faucet. The temperature is whatever is in the pipe. If you live in a hot climate where the ground remains hot almost year around, the water will be warmer. If the water that comes out of your cold tap is normally seemingly freezing, so too will the water that comes out of this device. The company makes another more advanced “bells and whistles” model if you want to hook it to your cold AND hot water supply. I did not think I needed that feature – installation is a LOT more complicated, for one – and now that I am using it, I’m glad I decided the way I did. If I lived in a cold climate, I would consider the more advanced model with a hot/cold water blend and not just cold tap (i.e., the Neo 120 model that I have). • Contrary to other reviews, the device will not drill you a brand new door on your backside, nor will it violently launch you smashing your skull into the opposite wall in a watery, shameful mess. That’s fun reading, but it’s not fact-based. Whatever your water pressure (cold tap), then that’s what you get – which is adjustable with the topmost dial. (But that has a downside – see below) • This device will save you money on toilet paper. For sure. “Do you still use toilet paper,” someone might ask. Yes. Yes I do. But it’s much less about cleaning and much more about drying off when using one of these. • I’m sorry to be gross, but even for a guy like me, handsfree washing of the back bumper is HIGHLY preferred to smearing around your trash like car wax. There is a reason why “snobs” love these things. Did this product make me a bit more of a snob as well? I don't know, but if it did, I'm now a snob and that's fine by me. • It also saves on your stain remover costs. Think white underwear. See bullet point above. • Aesthetically it is quite nice. I don’t have guests over in the middle of a pandemic, but once I do in the future, I will be interested in their potential interest. Think about it. You are a guest in someone’s home and you see this. The door is locked. It's just you. Why not give it a try? ???? • The price is very reasonable for what you get. The parts that could flood your house (water connections) are METAL and appear strong. There is no need for a wrench, which is very useful at breaking things not designed to withstand one. What I don’t like: • Installation (of the product onto the toilet, not the water connection) can be tricky depending on your current setup. I recommend a package of those cheap, long plastic hinge bolts. (The metal ones you likely have now are probably really gross as well, so replacement won’t hurt. In my case, my existing screws were 1) far too short with the bidet wedged in, and 2) gross. • The little white swinging “door” that inserts down into the bowl (but not the water in the bowl) forms a barrier. When in “clean” mode (bottommost dial, 3:00 position), the spout will spray water, not on your back bumper, but on that back of that little door. In “wash” mode (bottom dial, 12:00 position), the spout will drop down below the door to work. All of this is automatic. What I do *not* like is the “catch” for the door. When sitting on the seat, the little door sometimes flies open (which impedes operation), and sometimes the water pressure in cleaning mode will pop it open as well. This is a prime area of design improvement in my view. The only reason this door exists is for nozzle cleaning, either the machine doing it in cleaning mode or you manually opening the little door to manually clean the spray nozzle. Yeah – wear gloves. I see the appeal of these features, but there must be a better design that would accomplish the same result. • The water pressure control dial reminds me of the clutch on the riding lawn mower I used when I was 15. I would *ease* off the clutch and the mower would inch forward and come to speed. But if I did more than ease off it, the front wheels would clear the ground. Same here. The knob turn distance between 1% flow and 75% flow in this device is very limited. (This is due to the valve design, another sure place for improvement). The distance between 75% and 100% water flow on the knob is really the majority of the turn. (The valve moves from 12:00 to about 3:00 position). Go easy on this dial, especially at first. So if the full turn of the knob is 12:00 to 3:00, 50 % water pressure is like at 12:30. Anything beyond 1:00 is full pressure all the way to 3:00. • This has nothing to do with the functionality of the product, but some people shop less for utility and more for aesthetics. More color choices would appeal to such buyers. This is free advice to the company. Overall, the device is something I have faithfully used every day since installation (so, a bit over a month). I never thought I needed it until I had it. Next I may even switch to bottled soap instead of bars. Five stars.
