Meet the PYRO: an awesome device that lets you launch fireballs from your open hand. This wrist-worn device features 4 separate chambers for multiple shots. The wrist strap is adjustable. You also get a remote device to get more out of PYRO. The remote switch fits discretely in your hand and activates with the squeeze of a fist. The developers encourage you to use their Flash Packs to put PYRO to use.
PYRO is not a toy, so you want to be careful how you use it. Nevertheless, it is designed to take your game to the next level. It can be yours for $174.
