Review (5/5): Flosser refill
I bought this for my spouse, who always complained that his teeth are too close together for using a flosser. And of course flossing with just the thread is a little bit difficult when it comes to back teeth.
He is very happy with this flosser. The thread does not shred between his teeth at all, so he is able to do a decent job using just one refill per flossing session. Economy matters.
Naturally we would have been much happier if the refills (and the Hummingbird flosser) were made in the USA. As it is, it is made in China and the quality may not be consistent. However, so far - so good. If he runs out of refills and the flosser device still runs, I will look for another box of the same.
