The only thing I regret is the "relatively" small sensor angle of infrared history. Tested at a 450D, 500D and 5D the trigger is actually just outside the camera sense similar to a TV because the reception sensor was mounted on the camera front. (With my 450D where the yellow LED illuminates always self-timer).
For me it would be just more convenient if you could also trigger behind the camera. So you have to always keep the FB front of the camera.
Otherwise great thing and easily stowed. For the price absolute recommendation)
