I bought this charger to use on a vehicle that I only drive every few weeks or months.  The last time I went to start my vehicle, it barely started (from lack of use).  So that's why I decided to give this charger a try.  Figured it'd be cheaper than buying a new battery, which I've already had to do once already from lack of use.

Anyway, this charger couldn't be easier to use.  Just put it on the dash and plug it into a cigarette lighter outlet.  That's it.

I let it charge for a couple weeks and the next time I went to start my vehicle it started right up.  Sweet!

The only reason I gave it 4 stars instead of 5 is because it's advertised as having "an ultra-bright blue LED charging indicator".  It has no such thing anywhere on it, as other posters have mentioned.  Not sure why they falsely advertise this.  Not having the indicator is not a deal breaker for me, but I feel like they shouldn't advertise it if it's not really on there.  So minus one star.
