CVS claims that its replacement electric toothbrush heads fit all Oral-B electric toothbrushes except the Cross-Action? Power and Sonic Complete?.
This is not true. I own the Vitality?, and it doesn’t fit worth a damn.
This is a perfect example of the adage “penny-wise, pound-foolish.” These brushes are $17; Oral-B’s are $23. I thought compatibility claims were true and bought the less-expensive brushes. Whoops.
I always get the manufacturer’s replacement parts. It just saves my sanity. (and the replacement heads for my Phillips Soni-Care toothbrush are a LOT more than $23!)
I hope you get your money back.
