Review on 📸 Wireless Shutter Release Intervalometer with LCD for Canon EOS RP, Rebel T6, T7, T7i, 5D, 6D, 90D, SL2, 6D II, 5D IV, SX70 HS | Fujifilm GFX 50R, X-T3 | Olympus OM-D E-M1 Mark II by Ryan Bennett

I found the instructions a lot easier than I thought. I agree that it takes practice to become comfortable in the field. I like that I don't have to point the transmitter at the camera to release the shutter. I haven't tried it, but they say you can be 190 feet away and still activate the camera to take a picture. In this sense, I can prepare a shot involving myself or someone else without being close to the camera. The only downside I see is that the receiver sits on top of the shoe in the camera and precludes adding a flash. I think with some creativity you can attach the receiver or flash to the special grip that is added to the camera. All in all, this is the best trigger I've ever bought!
