NOCO GB70

What are your thoughts on the Noco GB70 jump starter pack? Does anyone own this product? I've heard some negative things about it but then again I've heard some positive things. Thinking about purchasing one for myself.

I own the GB40, and I absolutely love it. Works in all temperatures, the clamps are great quality, jumps most gas engines. I even drive cars with dead batteries into the bay with it, no problem. I also use it as a battery for bench testing components, or testing fuel pumps with the tank out of the vehicle. The manual override feature is priceless.

The only downside I can think of is recharging time. Using a USB cable, it takes 6+ hours to go from fully discharged to fully charged. In other words, if you drain it, the work day will probably be over before it comes back to full strength. Would still recommend to anyone, regardless.
