Review title: brush head problems; poor design
Product review: Product works fine, but the head design leads to a buildup of gunk and slime. The head seals leak, and unless you disassemble the unit after every use, you get a buildup of slime inside the unit. Very poor design. I switched over to oral-b and have been very happy.
