Title: Count the bristle groups on brushhead
Review: Target now also sells their own brand of "Oral B" replacement brushes under the label "Up and Up". They are the same as the ones sold here at discounted prices. They are of very low quality. I tried Targets. They do not fit properly, the connector part is slightly bigger. They do come loose and fall off in my mouth, there is not the same vibrating motion, they are a little rough. Also, I closely compared an off brand one to an Oral-B and found that there are less bristles on the cheaper one. The bristles are in little groups: Oral B=26, offbrand=18. So, you get what you pay for, I am afraid. Still, Oral B could be kinder and charge less for these simple little things, we know it costs very little to make them. Note: there should be "Oral B" inscribed on the arm of the replacement brush heads. If it is not there, it is definitely not theirs.
