Bests & Worsts Reviews from Amazon

If I had written his review yesterday I would have given it 5 stars. It has worked spectacularly. This said, today I was charing my truck battery. All was fine, when I looked out to see smoke coming out of my hood. The thing was fully on fire! I am so lucky I saw it in time. I could have started a serious fine. I am hoping I can get my money back, but I don't even know what the warranty is. This thing is dangerous!
