Call me crazy, but using a "High Voltage" pet brush doesn't seem like the safest thing to be using on Fido. Although, the manufacturers claim it can kill fleas and ticks with extreme prejudice.
Naturally, crazy Chinese products like this need to be approached with caution—because it could very well kill Fido with extreme prejudice. I'll bet this thing will be repackaged in a few years as a way to stimulate hair growth in humans. Just wait and see. [Alibaba via BaxterBoo via CNET]
