Oh wow! I just checked the SAME listing again (that's in my order history) and they have changed it YET AGAIN so now it is a listing for a complete knock-off Philips Sonicare toothbrush...not just the brush heads, but the brush body itself. Of course, I still have an "order again" button in my order history. For reference, when I originally ordered the brush heads, they were $15.99. The brush in the listing now is $59.99. This is insanity!

EDIT: It does appear they finally removed swaths of old reviews. Finally.
