Anyone use the Harbor Freight solar panel kits?

Some people don't enjoy searching the Internet for the minutiae and exotica of a subject. The HF and other kits don't require learning about the advantages of mppt over pwm or the why of monocrystalline panels for those who could care less. For a low price they can get a system that works and is easy to set up and understand. Not the best. Even the hobbyist/experts on here have trouble designing the perfect system for a member that wants to gain a couple of days camping out of their two batteries.
