If you can afford the OEM version do yourself a favor and get it. This does what it is advertised to do but there are several shortcomings. I am yet to get the camera to switch over from this to the battery in the camera automatically.<br /><br />Update: I initially gave this three stars but have since changed it to one star. As mentioned earlier, I was NEVER able to get this grip to automatically switch over to the battery in the camera. I just bought a used OEM model and the differences are phenomenal! Camera identifies the grip properly (something this model will not do) and switches over when the battery in the grip depletes. The battery door latch on the OEM model actually has electrical contacts which helps the camera know what grip is attached. This model does not have those contacts and therefore the camera is unable to tell that an OEM grip is attached. This is probably why my camera would shut off when the battery in the grip died and not come back on until I removed the battery tray from the grip!
