I have had the opportunity to test out the Venture 35 + Nomad 10 Kit from Goal Zero only once so far, and that time was while I was at work. I am unable to do any preseason scouting on foot this year. My uncle and a couple of friends and I will be flying in blind except for online scouting. I also purchased the Goal Zero Sherpa 100pd and the Nomad 20 solar panel. After our September hunt, I will leave a more in-depth review. But for now, when I was able to use the Nomad 10 solar panel, it was a overcast day and it seemed to charge the Venture 35 just fine. I am a field mechanic so I was able to set it out to change while working on a piece of equipment. Though my experience with these products is limited, I wouldn't hesitate to recommend Goal Zero products to anyone. So far they are great. The build quality is superb, and it definitely does not feel like a China cheapo.
