recommended by my dentist [SEP] my dentist recommended i purchased a water flosser but the one he was selling in his office was almost i looked them up and found that they were all considerably cheaper online i m extremely happy with this one the best feature is that it s cordless with the exception of when it s charging of course i ve had mine for a few weeks and i ve only had to plug it in once so the charge is lasting for those of you who ve never used a water flosser before they can be powerful and messy with water getting everywhere so it s best to keep and use them in the shower so that the water is confined contained inside the shower during use this was actually my dentists recommendation so this being a cordless flosser was very important i usually get about flosses in before having to refill the water reservoir which is very simple this one does come with several tips so i tried them all after settling on one i think having several different options is nice so that you can find the pressure and kind of tip that works best for you and meets your own unique needs overall i think this water flosser is great it does exactly what i need it to do and i got it for a fraction of the price from the dentists office i would confidently recommend it to others for anyone looking to buy water flossers i hope my review is helpful to you
