Bought on suggestion of Dentist as good (and easy way ) to floss a new "bridge" being "installed" and rest of teeth/gums obviously. Working great so far, but a feature that would have been nice, is a "lite" that is on when being charged, and goes out when charge is complete. Something that shows the batteries degree of charge, would be nice also. Just guessing otherwise, and going dead in middle of flossing is a "pain". Happened to me once already.
Seems to work well. (Won’t know for sure until I see the periodontist again.) easy to use, but I wish the on/off switch was easier to use, as you really want to be able to be sure to turn it on after placement by the tip in your mouth, and turn it off before taking it out. Dismaying tendency to spray the bathroom while fussing with the switch.
