Arg, I'm an international customer, why is the shipping so expensive?
It costs money to send this kit internationally. I do combine shipping, so if you buy another kit, additional shipping is $2.

Should I purchase the 1 or the 2 fan kit?
With another fan, you get more ventilation, however, you do get more noise and decreased battery life.
It just depends on what you want.

How difficult is this kit?
1 on a scale of 1 to 10, basically black to black and red to red wiring.

How much time does this kit take to put together?
Between 5-15 minutes.

How long would a 9v battery last?
Roughly 2 hours (using 1 fan).

Do I have to use a 9v battery?
Nope, if you want, I offer just the fan (which will run on 5v). You can wire it into an LED kit if you want. Just connect the red wire to VCC/+5V/V+ and the black wire to GND.

Does this kit fit both Thomas and Guy Helmets?
Yep, the Thomas helmet is self-explanatory. If you want to add it to a Guy Man helmet, you will need to cut a piece of plastic to size to fit in the bottom chin area of the helmet. That piece of plastic will need to have a hole cut out of it to hold the fan.

Does this kit fit all helmet casts?
Yes, it should. I know that different casts have different vent holes and these fans should fit all helmet casts, from the smallest to the largest.
