The only genuine battery I could find (genuine looking ad I should say) was on mobile-mate, even then I'm not sure if it's a grey import.
S5 is dying quick and I just want a genuine battery to replace the old one..
SS has a fairly good reputation and you are much safer buying from SS than most other HK-based ebay sellers.
I'd give it a shot, since it's only $13 delivered the risk is fairly small.
