Bite me Digi-boy.
I purchased it and as I said, if you had reading comprehension, it might work for a ripe beginner or a kid. Other than that it's a waste of money. You can tell Joe I said so myself. Saying a product is dumb isn't "knocking" anyone. I don't know the guy but I do know the device was a complete waste of money.
It's pretty sad when one snake oil salesman has to white knight for another one, then uses an appeal to authority. I don't care who the guy is, he sold a dumb product. Now put on your readers fella: "It's dumb and all but useless except for ripe beginners and kids."
