It’s small and light weight. This is my second time buying this. I bought one for my sister for Christmas and they had to use it twice. She loved it so much that I bought one for my son for his birthday and funny enough the next day he was going to work and his car wouldn’t start. It started the car in one try. I charged it the night before I gave it to him. The price is very reasonable it’s so small you can keep it in your glove box. It would of been a big bonus if it came with a case. I actually bought a case for him to keep everything together. It charges fast. You can test the battery so you know when to charge again. Your only suppose to charge every couple of months so it holds a charge, that’s s big plus. Who knew something so small and light weight could start your car. I’m going to get one for my car, because you just never know you want have to worry about calling someone for help or waiting around for someone to jump start your car. I Highly recommend this product.
