Amazing Product
it’s been really convenient. The 300ml tank is plenty for a thorough cleaning, and the pressure is strong enough to get between teeth without hurting gums. I love that it’s portable and rechargeable—perfect for travel or daily use at home. The IPX7 waterproof rating makes it easy to clean and safe to use in the bathroom. Overall, it’s a handy, effective tool that has noticeably improved my oral hygiene.

Excellent dental flosser
This purchase is a game changer for me. I see my dentist every 3 months for a check up and have always brushed twice a day, but still my gums seem to bleed and I am told off by the dentist for not cleaning them properly and I must floss etc etc. My teeth are close together so conventional flossing is difficult although I give it a go. Anyway, I decided to try a water flosser, based on an article I read in the paper and in fairness my dentist did mention them a few years ago, and what a difference it has made. I chose this one because reviews said it was easy to operate and it is. The reviews said it would hurt intitially and it does The reviews said that the pain goes with regular use and it does. For those new to this purchase, no need to plough through the instruction. Simply fill with water via the transparent little stopper at the bottom. Do not interfere with the long tube inside, there is nothing for you to do with that. Choose which head you want and place it onto the end of the device and off you go. My first experience of using it was laughable, as I kept opening my mouth at the wrong time, and also managed to shoot water in my eye and all over my t shirt but one lives and learns. Following my first use, I could not believe the amount of debris from my teeth left in the sink and it made my gums bleed a lot and it hurt like hell. I persisted and tried it the next day but this time, it hardly hurt at all and the debris was much less. Over a week of using it and my gums are in much better condition and are not bleeding at all and there seems to be hardly any bits of food being stuck (I do love nuts and seeds). My top tip is to enclose you mouth round the device when switched on and keep it closed, spitting out the water when it is switched off. You will easily get the hang of it. The battery lasts for ages so that's very handy too. I will update on here after my next dental appointment and this time, hopefully he will not be trying to persuade me to see the hygienist again ! Excellent value for money and my teeth and gums feel transformed !

Hard to master..but definitely worth persevering 🤣😊
I purchased this water dental flosser after my dentist said my flossing between a new crown was not that great 🙄 I was using the teepee interdental brushes but it was obviously not doing an adequate job! I read about the water dental flosser saw it was on a good offer on Amazon so thought ideal..give it a try. I have to be honest the first use I ended up with water all over my clothes ,hair & bathroom! I did read in the instructions you should leave mouth open slightly whilst using...but resulted in water running everywhere. I discarded it for a few days...thinking...waste of money. However I had another attempt & this time gently closed my mouth around the jet tip..blast for a few seconds..turn off spit out water & repeat...this actually worked😊 ..I had a few mishaps but ..getting better every day 🤣 I am so glad I persevered. It actually does an amazing job. I tried a test....I ate some nuts which always seem to find their way between teeth & gums. Firstly I used my interdental brushes..thought I had cleaned sufficiently..but....then used the water flosser....I couldn't believe the amount of food that came out. I then tried the other way round..I ate nuts..used the water flosser first..lots of food came out..then used the brushes...couldn't find any remaining food ! The flosser feels comfortable in the hand the tank when full is enough for a full clean. I used warm water as it felt more comfortable especially on sensitive teeth. Firstly I used the soft setting as advised but have progressed to the clean setting. I really think it makes my teeth feel cleaner 😬...Will update on my dentists opinion in September 😁 I found the bottom water inlet opening a bit fiddly so detach the tank & fill from the top ( personal choice) The charge is via a USB cable..the adaptor is not included but that's no problem as I have many for mobiles & other devices. I like the different settings. Also I charged on receipt & have used twice daily for 12 days.....apparently can last for 30 days...a bit like my toothbrush I guess.. Although 5 jet tips are included I will only use the two standard ones. So after nearly.throwing in the bin..I am so glad I persevered as I am really happy with the results now. Definate 5/5 for the product ( a bad workman blames his tools..so they say 🤣) The dodgy start was more due to me than the product ! I would reccommend ....especially when on offer at such a good price. The product also has a two year guarantee. Update 🥳😁. My dentist commented on the improvement of my cleaning of teeth! Usually I have a scrape & clean but he decided I didn't need it this time !!! Thus saving £75... so the water flosser has saved me money!! By the way..I have really mastered it now🤣...& find it quick & easy to use.

The best dental tool you could own
Wow! What can I say?! Flossing has always been a horrid thing to do as I often cut my gums and always felt it was pushing the plaque into my gumline. Never felt truly clean. This machine is incredible! Took a couple of attempts to get it right, but now it's easy to use. Irrigates between the teeth and gumline beautifully and has multiple options for pressure, massage, children's option. The device came with multiple heads. One for the flossing, one for the gumline and a tongue scraper. Since I purchased this item two weeks ago, I haven't even had to charge it again yet. Lasts a very, very long time. I recommend using room temp water as the cold can make your teeth very sensitive. The best way to describe the effectiveness is to see that it really is night and day, with regular floss. Regular floss = toilet paper. This machine = bidet. Can't beat it.

Improved Oral Health
Effective but the buttons should be positioned differently to enable easier access. Takes a little while to adjust to the potential power of the water jet. Amazing how many food particles it dislodges. Overall I think there’s bee an improvement in my oral health.
