I got one for Christmas one year. To say I was disappointed would be a bit of an understatement. After watching The Wizard my expectations were pretty high.
Suffice it to say, the glove did not live up to the hype. As you said it never really worked. I got it to work somewhat on Tiger Heli
I could move my hand and the helicopter would mostly follow my movements. To this day I still frown on motion controllers because of my bad experience with Power Glove. I own a Rift and refuse to buy Touch controllers because of frigging Power Glove! Power Glove scarred me for life!
