Solid performance and very well made.

Was a little skeptical this would provide enough power, but after an eight day camping trip in northern Arizona I can say this one goes with me everywhere now. It spread out perfectly across the windshield of my Xterra. Clipped it into the wipers and my roof rack to keep the wind from blowing it around. The setup was to run the main line into the cigarette outlet to keep the truck battery charged. I also used the panels USB connectors to charge devices. It pushed out enough juice to keep my 50qt ARB fridge at its 32 degree setting in temps that were in the 80's outside, with the frig sitting inside a black SUV that was much warmer than that. While doing that it also provided daily charges for two iPhones, one iPad, one Samsung phone, and a charger for batteries for two full size Nikon cameras. The frig was always on and we usually had two to three devices plugged into the system at anyone time.
Positioning to get it into direct sunlight is needed, of course. But it was surprising how little light was needed to get at least basic current flow going. Early morning and twilight saw it producing energy, thought not at the full 80w. Ditto on a partly cloudy/overcast day.
We hit a few days of gusty winds on the trip. The tough cover and clip loops worked well. It flopped around, but no apparent worries on wear and tear. It folds up very compactly for storage with a heavy nylon cover protecting the panels. An outside pocket helps keep all the connectors together.
