Ok, I was skeptical at first, because well, fireball shooting marker, but Pyro Pen delivered for me. I read some 50/50 reviews online. Some people are having a hard time getting the device to work consistently, or just work at all. I've not had such a terrible experience. My Pyro pen as worked exactly as advertised. If you set the device up the proper way it seems to deliver on point, every time. I've had no delayed shots...or jammed shots. It's been great so far, mind you I really read instructions and take good care of my things.
If you don't like the idea of being able to shoot a fireball from your magic marker like a ****** wizard, you won't like Pyro Pen, otherwise you're probably going to love it. I've already found a few cool ways to utilize in with other effects. Add to cart!
