To me, when a company (always Chinese, it seems) says they use “Samsung” or “Sanyo” or “Company” cells, it’s an immediate sign of shadiness and shittiness, and you shouldn’t deal with them.
That’s like saying your new car will be a “Ford” or a “Chevrolet”
I mean, Ford makes Mustangs and Pintos…so basically it’s telling you nothing at all.
