I need the remote release because it pointlessly unfortunately can not make a rational, self-triggering, HDR bracketing for stand mounting with the E-M5 (I hope but still on an appropriate firmware update from Olympus ... well hope dies last ... )
The important thing is not much additional Geraffel was take.
Therefore this version is optimal with short spiral cable.
The remote release is very easy and works like the 'normal' shutter button on the camera.
If you push the release button forward, then it is locked and represents the needs it then 'continuous fire'.
Absolutely OK for the price.
