New Insmart portable cordless oral irrigator dental water flosser NWOT

New and never used, but not in original box. Recommended by dentists, this is much more efficient than flossing with string and prevents many issues from gum disease and plaque build-up to problems with implants, bridges. Braces, and tooth decay. Easy to use. Hygienist recommended using it in the shower, but it is portable and can be used anywhere. Holds a charge for a very long time. (I have one that I use that is exactly like it). I purchased this one for my daughter, but she had one already. She opened it and kept the usb power adaptor/transformer brick that plugs into the wall, but any block used with cell phone or other charger will work. Everything else, including the owner’s manual, is in the listing.
