Review (1/5): Junky design makes this brush useless
Worked well three times, then the on switch became inoperable. Junky design mentioned by others is a fatal flaw. The on-switch and temperature buttons are on the handle and the temperature display keeps reverting to Celsius while fluctuating wildly. When it worked the brush did a good job of smoothing wavy shoulder-length hair (pulling out a fair amount along the way because the hair has to be gripped deep in the bristles and pulled forcefully). Could be that I got a brush with a defective on-switch but I would not take a chance on another one.
