Query: WORTHLESS! BUYER BEWARE!

This product is good for nothing more than jumping your battery! It is way to expensive for just this and it's heavy. If you try don't like it and try to return it to Ambient, they charge a 25% restock fee, gift or not! I would not buy this again, it does very little for the hefty price tag.
