i thought about buying one, but they are still kinda pricey and the quality kinda meh, i went with an offbrand, which has not failed me since i bought a few years ago, apparently it got discontinued because it was too good, and people were not buying its cheaply made versions. i also use a rotating oral-b as well.

the free replacement heads were a selling pts, and you can buy it cheaper and dont need to invest in expensive sonicare ones.
