Terrible product! Doesn’t work well at all. Not worth the money!

Flat head Doesnt clean as well as multi level brushes

These replacement heads do not spin like the OEM heads do. I’m tossing them and going back to the originals.

so disappointed me

These are very cheap and small. The round part of the brush barely covers your whole tooth and they do not feel the cleanest after. I have to brush for at least 3 minutes for it to feel like I brushed. You do get alot in the pack so it's good for the price but the quality is lacking.

I've used a number of generic Oral-B replacement heads over the years, and never had any problems. But after using this one for a couple weeks, I noticed that if I wasn't careful while brushing my teeth, the metal spring inside the brush would actually nick the inside of my mouth.I wasn't sure why, but I compared the brush to another generic brush I had been using before, and the metal portion (in the little oval in the front of the brush head) extends an additional millimeter or two beyond the generic brush head I was using... and I certainly never had this problem with those brush heads.Anyway, I suppose it's a good price for a 20 pack of these, but don't want to risk cutting up my mouth.. maybe these are fine for those less sensitive than me?

Brush heads are smaller than what I'm used too and I find that very annoying. I don't feel like I get my teeth clean. Bought 20 of these darned things so I guess I'll be unhappy for many months, until I finally decide to chuck the rest and get my regular brush heads.

Not at all the quality as the brand of Oral B. Very disappointed with performance.

Bristles will not last more than a week.

Did not fit my walmart brand toothbrush too well, but it does do it's job.
