Title: Don't buy a Interplak tooth brush.
Review: I have been using interplak for over 20 years. I think the rotary action is the best way to clean ones teeth. The first one I bought had an electric cord attached to it. It lasted for many years. Then they stopped making the brushes so I had to buy one with a battery. In the first battery tooth brushes the battery lasted a little over a year. You can't just buy a repayment battery you have to buy a new tooth brush. Every time I buy a new one the battery last less and less. I bought one 6 months ago the battery died. The warrantee had run out so I bought another one thinking that I just got a bad battery. Now the one I just got is not holding a charge it starts to slow down before I finish. I don't know why they don't make one with a cord.
