I was quite pleased over a product that is easy to use and produces good results. The price was also great. It will become my regular hair cutting product. Thanks Amazon for making it easy, safe and economical.

The unit worked out of the box. My wife had no trouble installing it. This is our second and only time it has failed. I think a person should consider how many times they actually plug and/or unplug. With this device, plugging and un-plugging are often required. On both units, one port works for 1 hour or less at full brightness. So you have to be pretty aware when plugging and unplugging.

Good Review
