Amazing teeth hygiene product
This Water flosser, is one of the more reasonably priced I found on Amazon. It comes with clearly printed instructions , which are easy to read and understand . It has a choice of flossing jets to suit all users and their requirements, as well as a varied speed for users . I have sensitive teeth and gums that bleed easily so have started on the sensitive pulse for the first two weeks then moved onto the normal mode. Even after cleaning my teeth with an electric toothbrush and flossing between teeth, this water flosser can still remove debris hidden in between my back teeth , which is amazing. It does spurge water out whilst being used, so use inside the shower cubicle, put your head well over the basin, or wrap a towel round your clothing to prevent wetting your clothes. The battery has not required charging yet and I use it twice a day. I have been using it for two weeks now, and ,this is the third week, so its holding a good long charge there. I found it does not remove plaque as such, it removes debris lodged in between teeth , and softens the plaque making it easier to remove with interdental brushes. It does make my teeth feel cleaner on both sides and they do not look as stained as before. Combined with interdental brushes and flossing, as well as electric tooth brush , I am pleasantly surprised how well it has worked so far. I would recommend this water flosser.

Excellent product
This product arrived very well packaged. For the price this product has left me pleasantly surprised and it works perfectly so far at 5 different speeds. The nozzle came in separate rapped packets. It’s a bit tricky to get used to as water spirits everywhere at first but not an issue as it leaves your teeth feel free of plaque and gives a nice clean feeling.

Cleans plaque easily!
It’s really good, perfect water pressure, even a little too strong as it temporarily made my gums bleed! Which is why it’s a 4/5 star. However it lasts a solid minute with a full tank and cleans well, also has a nice sleek design and a comfortable size to hold. It also comes with many different attachments and an easy to understand manual which describes how to use and charge etc. Overall this is a very good product for the price and I use it everyday!

Works really well and good value.
My dentist recommended getting one of these and said there’s no need to pay a fortune - which with this, I didn’t. If you’ve never used one before (like me!) it does take a bit of getting used to (be prepared to soak yourself and the entire bathroom!), but once you do, it’s so much better than conventional flossing. What I liked about the AUiEi is that it has 5 modes, including a child one and a Soft mode for beginners. It has a built in 2 min timer, but tbh the water vessel usually runs out first. It’s easy to operate, select mode and change the nozzles (some reviews said this was difficult and they’d broken nozzles in trying to remove them - I can only think they hadn’t noticed the small release button on the back). 4 nozzles are supplied inc an orthodontic one for braces etc. There’s two standard ones meaning 2 people can use the same unit. Instruction are good too. I’ve been using it once a day for about a month and haven’t had to recharge yet. Seems a well made and durable unit but only time will tell on that. It’s also reasonably priced. All in all I would definitely recommend.

Great product
This AUIEI water flosser is simple to use. There are just 2 buttons On/Off and Mode. Mode is displayed when pressed so its easy to get the correct setting, just keep pressing it to change the selection. The On/Off button is nice and big and in the right place for easy use. Recharging is easy, the cover just pulls back (so you can plug in the supplied USB-C cable). Its permanently attached so it cant be lost. Battery life is excellent, I can get around 3 weeks use from one charge. Filling is no problem, just open the back cover and fill from the tap. Cleaning is a doddle. Just hold the top and twist the water tank slightly and the two halves come apart. The tank can then be simply washed using a toothbrush. Performance is really good and it gets into all those awkward little places. I use the normal setting, which suits me but there are 4 other settings from child (gentle) to strong. I got this one after my previous make one just stopped working after only 18 months. I'm really pleased with the item and I would definitely recommend it.

Okay but flimsy plastic cover to charging socket soon broke off
It's okay, good sized water tank, pulses fine, and has a 2 minute timer. I always use it on 'strong'. I've had it for 15 months now. The tiny flimsy plastic cover that covers the charging socket broke off and then disappeared soon after I bought it. I'm not sure if this will affect how long it will last as it has recently started to stutter occasionally and I think either (1) this is due to water getting in or (2) the battery needs recharging but the red indicator is not showing. For a short while I disengaged the jet tip each night to let it dry. But it became almost impossible to release the tip. Yes, I press the release button but it got stiff and no longer works and the first tip broke! After flossing, I disengage the flosser from the tank, run the flosser for a few seconds with no tank, and then blow through the tubing as there are always surplus drops of water there. AUiEi give instructions on how to clean the exterior. But I'm more concerned that bacteria might build up in the 11" tubing from the weighted end in the tank to the tip (no instructions on how to clean the tubing) so I occasionally run it with a bit of bleach in a tank of water and then discharge it outside, and again with clear water to rinse. The tank is less easy to dry than a previous water flosser I bought from another company as the AUiEi tank hole is not as large. But I'm a convert to water flossers. I've had a lot of dental work done recently and they are very effective.

It WAS a good water flosser!
There really shouldn't be much in the way of "point of difference for a water flosser, as all they really have to do is eject enough water at a high enough pressure to shoot out all the little bits of food that make a home between your teeth but, as I've found with some of the cheaper ones, this is clearly more tricky than you'd think. Various issues like buttons failing and flossers refusing to give up their water have all plgued previous purchases I've made. So far, so good with this offering from Auiei, though. Not only does the water come out at a decent pressure, it doesn't suffer from any air leaks where you have to shake the flosser to remove to get the thing to actually work. The buttons are all positive, it has the air of certainly decent quality about it and comes with a couple of interesting extras which I've not had before, but which may prove useful to some - aside from the two standard tips, there is one each of a periodontal design and one orthodontal. The battery life has so far been superb - I've charged it twice in about 6 weeks of use (I tend to have a good 'ole blast after each time I eat!) which I feel puts this up there as the best I've had for battery life. There is a nice led indicator to show you when the battery is getting low, so you have adequate warning before it gives up the ghost on hosing down those teeth! The water tank is large, and it certainly pumps out a large volume of water when being used, so is necessary. The only improvement I think I'd prefer is to have a hatch to fill said reservoir instead of the more awkward dismantling of the two halves of the unit, to fill it. However, I must confess the hatch design does come with it's own flaws - rubber seals coming off and bits of food gatheriung around it which need regular cleaning, so it's "six of one and half a dozen of the other" as they say when it comes to this! All in all, I'm very happy with this flosser and would definitely recommend it. Update - 04-09-24. After 14 months of use, this has followed the pattern of similar water flossers - in that the battery has completely expired at around about the year mark! These cheap water flossers are getting frustrating now, with the regularity of the same thing happening - perhaps it's time for me to consider the more established brand/s..............................
