Replacement 3.7V 840mAh Li-Ion Battery Pack with Screwdriver and Stylus for NDSi/DSi

Pros: It has an excellent battery, will fit perfectly on a European DSi, charges in normal time just like a original battery, and the duration is roughly the same as an original battery. The screwdriver is also very handy if you do not own a screwdriver for your DSi.

Cons: It's not genuine if it can be considered a con. The stylus in the package is made of a cheap material and will be a little small for a European DSi. The screwdriver could be a little bit bigger.

Other: It's a great battery substitute for an excellent price.

Pros: The price is really good. In my country, it costs at least 5 times.

Cons: The battery seems very good, although I have not tested the battery life. The big problem is the Stylus, its quality is really bad, because the material quality is much lower than that used in NDSi and the worst is that the color is very different from the original.

Other: I need to check the battery life and see if its capacity is equal to the original.
