Works well, although I found the directions, especially for setting it up as an intervalometer, confusing. Mine works fine on my Canon EOS Rebel T6i Do make sure that you order the proper model for your camera. The units are basically the same, except for the cable connecting the slave to the camera. Also, while the slave unit will stay on over an extended time, the hand unit will shut off. Be aware if you're waiting a long time to grab that perfect shot. Very handy for catching some nesting hummingbird shots.
