Useless for mirrolesss
I'm using this on my a6000. First of all, the battery replacement on my copy has been impossible without ruining the lid. Secondly, there are so many unnecessary buttons that won't work on mirrorless anyways. There should just be a simple shutter on and off, with maybe a timer. I hope they make a new one. Also, it works about half of the time, even when pointed at the camera.
