Bests & Worsts Reviews from Amazon

Maybe I had bad luck, but my unit stopped operating 2 months after I bought it. I used it only twice. During the second time, after I turned it on, it burped once, the indicator light went off, and it became as dead as a brick. Switching it to another car's 12v outlet made no difference. Sending it for warranty repairs requires postage, a $20 "inspection fee," AND return postage, according to the manufacturer's website. Total cost is likely to exceed the purchase cost of this product. I hope my experience is not representative, but be assured that the warranty is completely useless if something goes wrong.
