Look good, but inferior construction.
They're inexpensive and they look good. Most of them seem to work well for a while. But I've had 2 fail long before the bristles wear out-- one only after 2 weeks of use-- because of inferior materials/construction. The wire which transmits the motion to the head breaks at the bend and leaves the head motionless: no brushing action. Better to pay a little more and not be putting these things in the landfill so quickly!
