I have a tiny mouth and this was too small for my molars
The floss dispenser is great. It's easy to hold and very compact. However, the width of the flossing arms (I really don't know what to call them) aren't wide enough for my back teeth - so my gums kept getting stabbed as I tried to force the floss low enough on my molars. I have a small mouth - the dentist uses child size lip and cheek retractors. If this won't fit over my back molars and gums, I don't think it would work for the average sized adult. It would work really well for children though! I wish they had more size options
