Title: Poor design......
Product review: After my Oral-B battery brush finally died, I decided to try the Crest brand battery brush. Big mistake! First of all, it took 3 different people to finally get the battery cover off to replace the two batteries. I used cooking oil on the plastic parts so it would come off easier the next time the batteries needed replacement. That did help, although I was surprised how quickly this would be necessary.The brush does spin quite fast and with a fair amount of power.Compared to the Oral-B, this is a poor design....plus it uses 2 batteries instead of one.Get the Oral-B. A much better buy, only one battery needed and better quality.
Would you say this review depicts the product in a flattering or unflattering light?
