Highly Reliable & A Must-Have

The GB70 has been performing amazingly well this winter. A couple of people have asked me for a jump start. They were surprised when I took this small booster out of my trunk and started their cars on the first try. I sold them both on the smaller GB40 version, as they had small cars. By the way, I also purchased the GB40 for my wife to keep in her car, and have the G1100, G3500, and G7200 chargers for varying applications. As you can probably guess from the number of Genius products I own that I have great confidence in them. Fantastic products - keep up the good work!

Yes, I recommend this product.
