So I found the same review apparently from the OP on Reddit, where the replies were less skeptical of the claims, and the reviewer responded to questions. Just to clarify, I think skepticism of random forum posts is quite reasonable.
Likely some of the reason for creating a new account here just to post this is less concern for hobbyists than some sort of catharsis. I've had a customer service interaction with the company in question that makes it reasonable to suspect that the reviewer's position is based on that experience rather than simply a premature product failure.
FWIW, I own both brands of panels and slightly prefer the ProProduct panels and would purchase one again if I needed another panel. My VE panels have not had any failures or real faults, though.
