Worked great, but only for a few months
I never write reviews, but had to say something about this.  I read the reviews before purchasing and hoped I wouldn't be one of the unlucky ones whose flosser stopped working after a few months, but it wasn't to be.  Really great flosser for 4-5 months, and having a bigger reservoir (via the travel cup) than most portable models that I could refill while flossing (I use 2 full cups worth - no idea how people manage with the small reservoirs) was ideal for me. BUT, after 4-5 months it wouldn't stay on.  I charged it, but it would run for &lt;1 minute and then shut off and flash yellow.  Disappointing, and not really worth the money for the length of time it lasted.  But 2 stars, since while it worked, it worked.
