I usually write any reviews but yes of frustration looking for a functioning wired remote release for my Nikon D5100 was simply too big. I will not at all beat around the bush: Plugging and work !!! (Had found in the past 3 years nothing you got to run remotely and permanently) But I do not mind spending 1-2 Eur more of the 5 test a cheap product at a Chinese restaurant around the corner to throw as back in the bin.
