Query: Junk!!

I purchased this item because it rated well in a leading consumer magazine. Well, it worked once (4 tires) and then quit. It just died and I could not get it to turn back on. I replaced the batteries and it came back on and worked for two tires and then died again. I replaced the batteries again but it would not come on at all. What a waste of money since it is not worth the time and shipping money to send this back.
