The Duatron Launcher

I was looking at stuff at walmart and I saw the duatron launcher. Why would you want to play yourself, you might ask? This would be something to help the testing of beyblades without time lapse.

We knew about this already for a while.
Duotrons have and always will suck.
They give one Beyblade more power than the other and sometimes does not even launch properly.

And as Ray Joker had said, we had already known about this a long time ago.
