Review (5/5): Highly Recommended!
Requires 16 hours charging before use.
Once charged, delivers a powerful and consistent brush action.
Pulses after 2 minutes brushing.
Only minor problem is that the package contains only one brush head - thus the low price.
Easy to find inexpensive brush replacements if you look around on Amazon.
I'll probably replace my brush head every 3 months.
Highly recommended!
