I have both the GB70 for my V8 Lt-1 Chevy Impala and the GB20 for the V6 Lexus ES350. Both work great and easy to use.

If it weren't for the price I would give it 5 stars. This starts my 96 Chevy Impala SS with Lt-1 V8 engine time and time again. I bring this with me everywhere I go. I don't carry jumper cables anymore. I live in Las Vegas so it gets above manufactures temperature while I am at work. 110deg F outside can mean up to 140 deg F in my car. It still works with no problems. I take it camping and charge my phone. I also have used it to help stranded motorists. It always works. I have had it for about 5 months now and I have only had to recharge it once after a 4 day camping trip and many electronic devices needing recharging. Also needed to start a few vehicles since then. I charged it up from more than half charged, back to 100% charged. It is back in my trunk ready to go again. I have the GB20 in my wife's car's trunk. It has saved her from calling a tow truck for the Lexus ES350 when she left the interior lights on. The GB20 would not start my Chevy, so it went in the V6 Lexus ES350, and the GB70 went in my Chevy. Love them both. Easy to use. Dummy proof.

Yes, I recommend this product.
