    5 Stars
    Great product!!!
    I bought this for my 2009 ninja and it works perfectly! Really easy to use just hook it up plug it in and select the proper setting. Charges all types of batteries. My bike was dead and it charged it to full and has saved me a few times from the battery dying. It's a life saver and a must have. Especially if you ride bikes. I would buy another one for sure and definitely recommend! I almost didn't buy it from other people's bad reviews but don't listen to others. See for yourself!
