Fits loosely and keeps coming off of my OralB Vitality.

Brushs too hard even though marked soft

The replacement head seemed a little stiff...did not soften up with use as some people had written...that wasn't my experience. After 2 weeks my gums were so sore and bleeding that I tossed all the heads in the trash.

These heads constantly slide off the end of my toothbrush base. I have a different brand of heads that holds on just fine, but these are unusable since they come off in my mouth while brushing.

Great price! But after a couple weeks my husbands and my teeth and gums both started to hurt. If you look carefully in the description there is no mention about the bristles being soft. If you ask any dentist they also recommend using soft brushes and these are certainly not.We bought "Compatible Oral-B Extra Soft Bristle Electric Toothbrush Replacement Brush Heads for Sensitive Gums and Teeth, 8 Count Refills" and they work much better and don't hurt our teeth. Not sure what we are going to do with the rest of these....

This item doesn’t fit this Oral B Tooth Brusg.
