Review (5/5): seem as good as the original
May be too early to tell, but so far these work great. The price was so good, I bought another package hoping to beat the price raise. One week and the price went up by more than a dollar. Still a good price when compared to the Sonicare original replacement brushes, so I did buy another package. I should be in good shape now for a while., since my wife and I have a total of 12 replacement brushes. 2 of them have been used now for a month and I still like them.
