    It Does What It Claims
    Been using this for about a month now, and it's doing exactly what I need it to do: keep my bikes charged and ready to go. The leads that feed each bike are long enough for most applications-- no need to buy the extension. I keep the charger between my two bikes for ease of use, and as a visual reminder for people so they don't trip over a dark colored cord stretched between bikes.Why spend $300 at the dealer for something similar when this does the job superbly?
