Review title: Clean teeth..but you'll have mold under the brush head.
Product review: Simply a poorly designed brush head. My teeth feel and look cleaner than with a traditional brush, but I had mold under the brush head within 1 week. My wife's began showing mold within 2 weeks. That is an unacceptable design flaw. The instructions state to remove the brush head weekly for cleaning, so Philips is obviously aware of the problem.
