With the price (and the power) can not whine much you

The batteries are fine. Naturally keeping out less than the original. The only problem my Canon 650D shows the battery as if they were full until they are empty, and then suddenly (if they are really empty), they will be shown as red, because you just have to change the second battery (bothers me not that).

For me, a good extension of my original battery! and pricewise they are tol !! I use both batteries are about 2 months and am very satisfied.

From me a clear recommendation if you do not mind that the batteries eventually need to be suddenly empty.
