Disclaimer: As you can tell from my blog post I know the guy who makes it but I have no economic incentive for posting this. I think it's a fantastic glow driver that will save plugs, engines and keep starting the 4-stroke beasts safe for everyone.
I post it here so that we can discuss glow drivers (I know there are more out there including Rcats from Central hobbies) and get feedback. What do you think of this glow driver?
