Bests & Worsts Reviews from Amazon

The overall function of the toothbrush is good, and I like the sensitive teeth bristles (reason for 2 stars), but the brush heads do not tightly fit on my toothbrush which results in mold in the brush heads. I’ve tried changing the brush heads but it doesn’t help. My picture shows how much mold is inside after skipped a single day of cleaning the inside (which shouldn’t be required). Very frustrating. I will say, I got my husband one as well and this isn’t an issue. I got unlucky with a design flaw it seems.
