Well, anyone who over-rates their batteries has already tipped their hand (business outlook) in my opinion, so I won't support nor recommend them on principle.
Safety isn't for sale (to me anyways), and even though I trust Mooch's ratings implicitly, I won't buy from any company that practices shady labeling. If they'll do it with their batteries, why would you think they'd not do the same thing for another product? It's the same folks at the top who make, or allow those decisions to be put in practice! (Just my thoughts mind you)
Efest isn't alone in this FWIW. I hold the same view of a few companies in this dept.
