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 model.<br /><br />I 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 longer.<br /><br />There’s only 3 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 flosser.<br /><br />The flosser charges via USB, but with a proprietary end (not A or C or anything like that).
