Snow Shovels - Cordless Electric

Never too early to start thinking about winter...

Has anyone used a cordless electric snow shovel? (see below if you read that questions and said "what the *#&^ is that?")

The online reviews are good but online reviews on retailers sites have become more and more suspicious. There are reviewers that I have followed for a while that tend to be trusted but I still wanted to check here to see if anyone had real-life experience with one of these.

If you have used one:
Did/do you like them?
What kind (brand) have you used?
Anything you don't like about them?
Does your wife use it? Does it work for her?


For those that are not familiar, an electric snow shovel is basically a mini-snowblower that throws the snow forward which is supposed to save your back from lifting the snow with a regular shovel. They are supposed to be good for things like walks and decks.
You can see one here or here. Or if you search youtube you will find plenty of videos showing them.
