Query: Price says the quality

I was excited when I first got this item. I told everyone about it. It's real cheap and it worked great......for 3 charges. I used the car charger 3 times and it's gone bad. Its only costed me under $6 including shipping. But if you do the math, it's costed me $2 per usage. Not worth it.
