I had some trouble with this filament being too soft and buckling in my extruder. This seemed to be an aberration, and Michael and Larry were very helpful in working with me to solve the problem and quickly send replacement filament. Otherwise the filament prints very well with no odor and comes on a large spool so it feeds reliably. I will be buying more, since they clearly stand behind their product and will go out of their way to satisfy / help.

The panel is amazing and it works as well as a wall socket for charging small devices like you phone or gps. Its doesn't have to be a super bright and sunny day for it to work. The battery pack that goes with it to save some of that energy seems to loose power over a few days no matter what rechargeable batteries you use in it. Other than that big floor, the battery back is great and works well to charge your small devices when its dark or clouded over.
