cordless water flosser [SEP] if you ve never used a water flosser before there s a definite learning curve expect to get wet the first few times if not more the learning curve and mess is worth it my mouth generally feels cleaner after using one but i don t love this particular modeli wanted a water flosser that wouldn t take up a lot of space on my bathroom counter this one is a sort of all in one with the reservoir built into the handle but i kept getting water bubbles in the tank tip which made flossing take a lot longerthere s only speeds low medium and high the low is quite low and because of where the speed switch button is it s really easy to accidentally switch speeds while using the flosserthe flosser charges via usb but with a proprietary end not a or c or anything like that
