Review (2/5): Heavy, didn't last
I got this for my travel kit. With two AA batteries, it's quite heavy. The heads are very small, and wear out quickly. Requires battery replacements often. The two minute timer just shuts off, no quadpacing or warning, not very useful. After six months of light use, just completely died.
I have an Oral B rechargeable rotary head at home, used for over 8 years. Much better on all counts. Much more expensive, but worth it.
