Water Flosser for Family Use, Oral Irrigator Non-Electric Safety Adjustable Faucet & Shower Spa, Water Pressure Dental Oral Care Tooth Cleaning.

I measured my household water pressure at 72 p.s.i. If your pressure is lower or higher, performance will vary accordingly.This is more compact and powerful than a water flosser with an electrically powered pump and a water tank. Who needs all that extra stuff? Household water pressure in a typical home is more than enough to make it blast food particles out from between your teeth. I've used it after eating nuts or dried fruit that sticks onto and between my teeth, and it does an excellent cleaning job.In fact, if you have normal water pressure, turning your faucet on all the way could hurt your gums. Before turning the diverter valve to horizontal and sending water through the nozzle, leave the diverter lever pointing down and adjust the water stream coming out of the faucet to a small trickle. Then, before using the unit in your mouth, point the nozzle at the sink drain, turn the diverter valve lever to horizontal, stick your finger in the water stream, and adjust the water pressure with the faucet until it is where you want it. I find that using the diverter lever on the side of the faucet adapter to turn it on and off is preferable to the on/off thumb switch on the unit.Put the nozzle in your mouth, close your lips around it, then turn the diverter lever to horizontal. Clean your teeth and gums by feel. If you try to use it with your mouth open and looking in the mirror, you'll have water everywhere. Be sure to be leaning over with your mouth near the sink when you spit. Turn the diverter lever down (or, if you're all finished, just turn off the water faucet) before removing the nozzle from your mouth. Be sure the diverter lever is down before leaving the sink, so somebody doesn't accidentally squirt water all over the bathroom.The package comes with a lot of plastic extra parts for adapting the diverter valve to various different sizes of spigot threads. If you have a well-known brand, up-to-date faucet fixture with aerator, you probably won't need any of those adaptors. The chrome plated metal one worked fine for me. It also has adaptors so it can be used in the shower, but I didn't set mine up that way because I didn't want to have to get in the shower every time I wanted to clean my teeth.Just a few things that could be improved: 1) Printed instructions could be more complete. 2) The included plastic hex-wrench gets cut by the metal adaptor because it isn't strong or hard enough. You may want to buy a metal Allen wrench at a hardware store. 3) I'd prefer a simple, compact wall-mounting bracket that could be screwed to a stud instead of the stick-on "mini-cabinet" with all the nozzles out in display -- I'd rather keep the nozzles in a drawer or medicine cabinet and have a small separate bracket on which to hang the unit.

My teenager has a full mouth of braces and uses this to keep his gums clean, as it's hard to floss under the braces wire. It was easy to install and easy to use. It has lasted quite well.

The sprayer works by itself, the problem is the piece that connects to the faucet for the shower head isnt strong enough to support a normal shower head or handheld Spray nozzle.Details:There is a metal ring on the inside that keeps the connector attached to the piece that connects to the shower faucet. The moment you put the shower handle or shower head on - it falls apart and sprays water everywhere. So this will not support the weight of a normal shower head.. I've owned it for less then a week and its fallen apart 3 times. its going in the trash tonight - so frustrating

I love this thing! My husband installed it but he said it was easy. I use it for a permanent bridge that I used to have to fish floss through. It really irrigates that area well and is so much easier than flossing that area. I wouldn't give up my regular floss for the rest of my teeth but it is great for very hard to floss areas. You have to be careful though, if your faucet is on too high it actually can cut your gums. As long as you control your faucet though it is perfect and so convenient. No more filling up a tank. You can use it continuously until you shut the water off. Great product!

It's far better than I expected it to be. As some say - who knows how long it may last - we shall see.It is what expected it to be, as described.However, the through put water aerator reduces that waters pressure to much for me - e.g., can't rinse my shaving blade while using it - to light water pressure. I pulled out the doubled screen and it helped. However, I wound up putting my prior one back in, since when popped it's screens, puts out a nice series of jets to wash stuff off with water pressure. One might have to otherwise possibly drill one center hole so had that within the stream of soft aerated flow. It does nothing to save water since one uses more over time to clean something in a millisecond of a water blast - rethink that OEM if read this.I am no crazy about the flex tube routing; and this one puts it's output at a 45 degree not 180 degree offset which matters. However I was able to face mine toward the back and keep all of that out of the front of the faucet - which is not a good idea, not gonna last that way.Anyway - keep in mind not to blast a hole in your gums and you'll be fine, or cause them to recede. Otherwise if used by an adult that gets all of "this" - it's a great, non-electric, no-tank required option.Not the best, but okay from what I can see. I would not mind paying more for a supremely designed and deployed design, e.g., off of a forked water take off valve to be independent of the faucet, or a better faucet design. -OR- a easily on/off constantly type, robust enough to hold up, 2-3x's a day on/off and not be a wet mess.Otherwise, I suppose this, as it is, is about it.I was able to better rout the flex hose with hidden stainless hooks to the holder they provide. That tape is super sticky, so careful in "temp" alignment, it will stick and be a problem, or live with it crooked.I hope that helps someone!
