Don't buy this [SEP] This flosser looked nice when I opened it. It came with an assortment of different tips and a charging cord. When I used it for the first time to check it out, it didn't have constant pressure while flossing. I wasn't crazy about that, but thought it would be o.k. anyway. When I tried to turn it off, it wouldn't . I thought I was pushing on the wrong spot. I wasn't, and when I looked to see, I had water flying everywhere. I kept pressing the power button, and it finally stopped squirting water all over. After I cleaned up the bathroom, I went back on Amazon for a refund. This may have been a faulty device,but I wouldn't suggest buying one based on what happened with mine.
