I saw this clipper on sale at Costco so I ordered one this afternoon.

For $30 and another $3 more for shipping isn't bad. It's twice that price on many other retailers websites including Amazon and Walmart.
My wife offered to use it on me when it arrives in a week or two. I showed her the videos relating to the product and told her it looks like it's designed for someone to use on themselves. She's free to try and use it on our toddler though. No idea if it's any good, but it looks well reviewed on Amazon. The promotional material seems kinda... gimmicky though.
