Great! At the begining.

Very good! I am of the same opinion: the batteries last longer than the original! Allow about 2 hours against least 1:30 to the original one in my case. Ability to plug on cigarette lighter (SUPER handy!), Made European or American, well thought!
However, about 10 months later, the clearance between the battery and the location to the latter on the charger increased, thereby preventing the loading of the battery. Product useless. To see whether or not isolated cases.
