We bought this product last year because my car needed a jump start for the first time. We were lucky the car beside us, we were in a self carwash, had this product and lend it us. I was amazed how easy and handy the jump starter is.We have used it 3x already and it works fine perfectly. I lend it to my friend who needed a jump start and recommended the product as well to have it the car handy - theirs was a bigger one and heavy. So far, I have no complaints or problems. Buy it for safety. It’s worth it. ☺️
