Review (1/5): Better Options Avail
I have been a fan of Sonicare for about 10 years. In April, I needed to order some replacements heads for my unit.
Pros: -
Cons: Since there are a limited number of brushes it seems as if they are stronger and often cut into my gums. I have had this happen numerous times on all three in the package. Also - it seems as the "blue bristles" change color rather quick. In fact, mine were halfway worn after the first two weeks.
Overall, I would recommend that you stick with basic replacement head. They have been around for years and are a good investment.
