Absolute garbage
The only reason these get one star is because Amazon won't let me give it 0 and still review.<br /><br />I bought these as replacement heads for my OralB toothbrush. I verified in advance that I had a compatible model. Since the brand name heads are pretty expensive, I was optimistic that these would be good replacements, even if I did have to replace them a bit more often.<br /><br />The first one broke after three uses. The second through fourth ones after two. Something on the interior of the brush head in each case snapped, making the brush head unable to rotate. So instead of having a ~$6 solution to a $16 brush head replacement problem, I now had a ~$6 manual toothbrush. I began this pack on a Sunday, ordered the brand name heads to replace them on Tuesday, and didn't have a working toothbrush by the time the real ones arrived Thursday.<br /><br />Absurd. Do not buy these. You get what you pay for in the realm of electric toothbrush heads.
