Review on Conair OptiClean Replacement Power Plaque Remover Brush Heads - 2 Count by Tony Winn

I bought this for my Interplak electric toothbrush. My toothbrush model number was listed on the back of the replacement brush head packaging. The replacement didn't fit: they were very difficult to fit onto the brush shaft and when I rotated them into position the brush didn't work at all. I had to put the heads on the brush at an angle to work and then they only worked sometimes. (I tried both heads in the pack, neither worked.) Total ejection. Revain gave me my money back (great Revain) but it solved my problem of needing brush heads to fit my electric toothbrush. I just bought a Revain Oral B 1000 so I had an electric toothbrush to switch to.
