do not 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 did not have constant pressure while flossing i was not crazy about that but thought it would be ok anyway when i tried to turn it off it would not i thought i was pushing on the wrong spot i was not 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 devicebut i would not suggest buying one based on what happened with mine
