Title: refill not good
Product review: I have had trouble with these refills. I've had my braun toothbrush for over 5 years, but find that these Oral-B Precision Clean refill brushes become loose and wobbly after about a month. This happened with my last order also; however I did not remember where I got it. Up to this time I've had no trouble with my toothbrush or the replacement heads.
Would you say this review depicts the product in a flattering or unflattering light?
