I have the hard wire part on the busa for quick connect, but the bike dosen't sit long enough to need it, it pig tail also allows me to connect a cigarette adapter, which I would used to power Tom Tom prior to it getting stolen from my truck.
I have two, one plugs directly into an outlet and the other uses a chord to plug it (more weather resistant), I use them on the jet skis and they do a great job. I bought my Dad the 4 bank charger, works great for keeping several batteries on a float charge. I bought my brother a 6v battery tender for his old harley and he loves it.
So I don't have any complaints about it and I have not heard anything from my family other than Thanks.....
