Input:
I expect nothing but the best from Canon and I wasn't disappointed with the RS60 E3 remote switch.  It is well constructed and easy to use...performs as advertised.  I also own the Canon wireless remote, but you need to be in front of the camera to use it.  The wired switch is essential for eliminating camera shake during long exposures and it does the job well.  Every photographer, novice to pro, needs this switch.
