Good start with the battery feeding directly into the Battery cavity. Nicely formed grip but the lack of vertical shutter release really nerfs the purpose of having the extending handgrip.

I still find the Ownuser grip a much better buy although it is a bit pricy at ~$125 BIN on ebay? Its dual vertical shutter buttons add huge flexibility and even out the role of the hands. Camera and OEM grips are typically made for right hand shooters. The Ownuser features 2 shutter release buttons facilitating left hand usage as well and even just giving the right wrist a break.
