Appears to be just as good as OEM unit
Still testing this unit. However it is much higher quality than I thought for 1/4 the cost of the Sony unit. It plugs in perfectly and has a nice case and a screw to mount the unit to the tripod socket as well. I haven't used the Sony, but if this stands up to the test of time, not sure I would buy anything else.
