OVERVIEW: I never tried a bidet before, but with the scarcity of toilet paper, I thought to give it a try. Wow! I will NEVER use TP again! I have never been so comfortable, so clean, so fresh! I'm a Primary Care Medical provider, and I can recommend this for my patients with mild to severe hemorrhoids, postpartum or post surgical peri-care or frequent UTIs. Everything is adjustable from water temperature, angle, movement pattern, aeration, water pressure, heated seat, air-drier temperature - this unit is amazing for the price. It converts any toilet into a very good quality bidet with minimal effort. Let's talk specifics.Installation: You will need an adjustable wrench (or pliers will do) and a large screwdriver (straight). You will also need an extension cord to plug this in. The power cord is only 3' long. Plug into a GFCI outlet only for safety. The included hardware has all you will need - including a 3/8" adapter for the hoses to attach to your water supply. You don't need thread tape as all the connections are low torque compression fittings. There is a small white nylon bushing that comes inside the 3/8: adapter. Make sure you install that on the water supply side (3/8" side) or it will leak no matter how much you tighten. If it leaks, you have it on the wrong side of the adapter. The supply line hoses provided are loo long for most installations, so I looped mine as it wasn't worth it to me to drive and get shorter lines from the hardware store. The lines are white supply hoses. You can buy steel mesh lines in shorter lengths if you are picky about appearances, but looping them looked fine to me.The installation instructions are weak, but you can figure it out if you know how to build things. If you don't, ask your handy friend to come help. It literally took me 10 minutes to install. They are very vague on the seat installation, so it bears mentioning that I loosely installed the adjustment plate onto the seat first, with the nylon screws sticking out, and THEN put the screws through the holes in the toilet. Following their instructions to install the plate and screws first resulted in an angle not being able to see to line up the slides and it was very frustrating. But my method worked easily. TIP: They don't tell you in the instructions, but the metal channels have to be installed with the edges down so they engage with the adjustment grip detents.USE: The unit has a small water heater tank that fills when you turn on the water. It has two power settings. When you first turn on the power, you see a RED LED for high power which will heat your water quickly - like 5 minutes. The water can be uncomfortably warm on highest setting, but it's adjustable. Medium is just right for me. The water cools a bit toward the end of the auto wash cycle in this setting, but it's refreshing.If you press POWER again, the LED turns GREEN which is economy mode. It takes a bit longer to heat the water, and results in the water getting COLD halfway through your auto wash. It's a good setting to just leave it on all day if you're around the house, but I recommend when you sit down to use it, press POWER twice to put it back in HIGH mode.CLEANSE is a no frills spray for the backside. You can adjust the pressure and aim with buttons.BIDET is a no frills wash for the ladies. Adjust water pressure and aim with buttons.DRY turns on the adjustable heated blower. This is NOT an "air purifier" as some reviewers state.AERATED injects air bubbles into the stream making for a wider more gentle water stream.MASSAGE moves the stream back and forward along the target zone to get you cleaner.It also has an adjustable heated seat and self-cleaning spray nozzles. Also has a cleaning mode to extend nozzles for brushing/cleaning for hard water buildup.RECOMMENDATION: For simplicity, ease of use and comfort, I highly recommend pressing AUTO and then AERATE. This gives you a fully automated cleansing wash, massage and dry and you don't have to press any more buttons. Ladies can press AUTO and BIDET for a fully automated feminine wash and dry.NOTES: The water pressure and stream intensity can be a bit shocking for first time users. The pressure is adjustable, but even on low it might take getting used to for some. Try the KIDS setting. But if you press AERATE, it softens the impact for a MUCH more comfortable experience.SEAT WARMER: Gets really warm quickly. I recommend you don't leave this on overnight, but turn it on right before you need it. It's warm in 1 min. Then shut it off as it will likely discolor the seat plastic it left on 24/7 for months.PROS: This works great and the price is affordable.CONS: No cons.IMPROVEMENTS: The ONLY things I can think of to make this unit better would be a nightlight that shines into the bowl (like a blue LED) and a back lit control panel for night use. Also, motion activated seat and water heating for efficiency. It's a waste to keep the water warm all day for maybe 1-2 uses per day.Hope this helps! Enjoy!
