I purchased one of their 100 watt suitcase kits 5 years ago, it has performed very well, really helps to give a boost to the panels mounted on the roof. Pretty durable as well, one time I left it on our metal rolling tonneau cover over our truck bed, next day found the wind had blown it off face down unto the ground, about 10' away from the truck.
Thought it was a goner for sure, after removing all the dirt, sticks, and rocks the wind had driven into every nook and cranny of the suitcase it worked as if nothing had occurred. Did lose the charge controller as it went through a major storm and it was not water resistant, ordered another from Renogy that is waterproof and it has endured a few storms without issue since.
