Great, firstly because of the dual battery compartment, because the NEX 5N occasionally somewhat 'weakens' when recording movies with a battery, secondly, because of fixed gripping ability of the small camera body to heavy lenses, especially in foreign lenses with adapters. Attaching the battery grip with some practice problems, seating is tight and precise. When using only one battery in the handle, the right side is taken into account (s. Operating Instructions, well illustrated, but English skills helpful). Tiny downside: For adapters with its own stand base for heavy foreign lenses of the pedestal of the adapter is hidden and can not be used. You just know will not regret. The battery grip has its own tripod thread.
