Review (4/5): Small investment that seems worth it
I have only been using this toothbrush for a week or so, but already I can tell a marked difference over the conventional brushes I had been using. The plaque removal is much more effortless with this brush and it has a stimulating effect on your gums.
I definitely noticed that the plaque levels have been dramatically reduced, and it does a much more thorough job of getting in tough-to-reach areas, which is a big help for a snaggle-tooth like me.
This brush appears to be the entry-level model, so I think it is worth a try for anyone who is curious. I am doubtful that the more expensive models have that much more to offer. The lack of rechargeable batteries may seem to be a problem with this model, but it also allows for more flexibility and easier replacement, as you can use standard or rechargeable AA batteries.
This one also lacks a detailed timer, but you're buying a toothbrush not a stop watch. This one has what's important: the cleaning power. It runs for 2 minutes, so you know when you've brushed at least that long.
The biggest drawback for the entire Sonicare line seems to be the expense of the replacement heads, but for the price of this brush it's hard to complain too much. Some have also commented on the fragility of this model, but even if I had to buy an entirely new brush every 12-18 months, it would be worth the 30 bucks.
