Review (4/5): Good replacement brush for a lot less money.
I have used several Oral-B model toothbrushes over the years and have tried many different brush heads. I always come back to the standard size like this one. It just fits my mouth and gums better than the larger ones. These generic replacement heads works just fine. There are subtle differences. The extra soft is more like a soft. Not near as firm as some replacements heads I've tried though. That's good. I think they slide onto the motor easier than the originals. I really can't see any reason to pay more for the original brush heads. These are a good value.
