I have deliberately chosen again with my A77 for a battery grip as me better is the camera in hand. What I particularly like the closure of the battery compartment, with this closure, it may not pass the rises of-times provided the tray. In general, the whole processing of the handle is very well done and fits great to the camera. What was also important to me that is the handle not creaks, my old grip on the Alpha 350 creaked namely a very short time and did not look wertig from the very beginning like this handle.
I'm talking about a very strong buy recommendation, with this type technology should not be saving for a no-name product you will certainly not have as much joy.
