Have you ever actually held and tested the controller and what was the protocol for testing that enabled you to label it as Junk? He probably would have listened to you if you had not started with the trash talking. Any time someone approached my paving company requesting a bid, I did NOT start the conversation by calling the competition junk. I am sure that you have some degree of qualifications, but there is also a place in the world for "Solar for Dummies", $140 is pocket change and the OP will learn more and faster than from any forum how fun and simple solar can be. He "might" aspire to your level, but he might simply enjoy a couple extra days camping without considering mppt, pwm, Lithium, or other jargon of the hobbyists. He can be enjoying solar within twenty minutes of opening the box. He can return it if it doesn't do what he wants.
