3 Strikes You're Out

I never thought I would have to use it. I bought a used 2003 Cadillac Escalade EXT (the cowboy pick up model). After one year, the battery refused to start the engine. I had bought a GM40 boost unit about 4 months earlier. I pulled it out and hooked it up. Wow, car started right up. In the past month I have had to use it THREE times - one was the evening after a great Christmas eve get together. Today, I bought a new battery. Three starts on the same charge and never gave me a second look. I had total confidence. What a great product to keep in the glove box. It saved me a tow truck service call so it paid for itself in just one use.

Yes, I recommend this product.
