Costly replacement brush heads
This is the best value in electric toothbrush, I've been using it for 7 weeks now and it's worth every penny. I can brush better than most people using regular toothbrush, but this electric one allows me to clean below the gum line better.<br /><br />However, the replacement heads are expensive; a 3-pack cost almost as much as the entire toothbrush!
