The Gun Counter

Have any of you fellow two wheelers used one of these? I have an S&S 113 cu/in high compression engine on my custom. It eats Interstate batteries like Pez. And I keep them connected to a good quality float charger at all times.

These things get pretty good reviews. http://www.amazon.com/PERFORMANCE-12-CE ... 334&sr=8-1

Yeah they are a lot of coin. But so is getting stranded and having to call a flatbed to pick you up.
