Review on Replacement Toothbrush Compatible Precision Sensitive by Jon Odom

I have found that some brush heads are loose, can pinch the inside of your lips and are much less effective at deep cleaning. However, some brushes are very similar to Oral-B brushes. So it's a mixed bag. I haven't explored them all yet. One set of brushes has a wider head which I really liked until it came off very quickly and turned into a terrible pinscher that didn't brush well. I threw them away. Another brush with dark blue bristles on the sides, in use for more than 2 months, all ok. The head is tight, does not press, cleans perfectly.
