Has anyone used these and are they any good? Wanting to buy one but I'm put off by (the very few) negative reviews on Amazon saying it isn't genuine, yet it seems to be sold by Amazon. Some of the reviews say that the battery is made in Korea and not China like the original. Anyone got any views on this? Seems like a decent price.
