I highly recommend this investment that lives up to our expectations! No they are not more efficient than disposable batteries, but they struggle to get comfortably to their height and arguments to prove it are !! Always at hand a load of only about an hour to two and the baby toy is no longer asleep !! The Wii is not cutting more with the left abandons psuique we think qd started playing live has put two charge! C is environmentally friendly and non c questionable because the battery has mountain lay stagnant ds Garage no thank you !! And especially my camera ds' photo yes I don not use it every day they do not discharge !! So I say thank you thank you thank you because in addition to this little apple green color is awfully nice!
