I have this one, had to replace it because I lost the very unique charging cable that came with it. There was another one a day ago that was usb c, price was the same as this. I'd say just wait till that one pops up unless you don't mind this charging cable type. I didn't think that was a problem when I bought it but the battery lasts 2-3 months. Within that time I lost the cable. So just keep that in mind.

Just bought, thanks! I missed this the other day so glad to get it this time. Tested to see if it stacked with the Get any 2 for $39.99 and it does not, but $7 is a steal.

Code not working. Just tried it at 4:00pm Pacific Time. It reads "The promotional code you entered has expired". Bummer!

Got in for one yesterday. Was about to just go to Walmart for a Waterpik after my 3yr old Oral B flosser died.
