Anyone fill me in on if this is worth spending $216 on?

 

what is it?

 

I guess it's supposed to help all of your cars electrical components work better.

 

it upgrades your major ground points by running additional wires to existing grounds , like throttle body , starter , alternator , for example . and uses condensers to stabilize
voltages under load . the blue light stays on , it's an LED so it won't drain your battery , mostly . does it work ? their dyno charts on a mazda 3 shows some power gains , and
alot people claim some good results with it , mostly

 

Thank you Bill. 💯
