Have the part of the Fuji XE 2. Whether it is absolutely necessary is another question. Anyway, it's considerably cheaper than the "original" (120, -). It is processed from all neat and metal. However, it has - as well as the other reviewers complain about already - some play on the hot shoe. 3 layers of paper under it and it stuck. The main function is to cover the open contacts for me. The bracket also prevents accidental adjustment of the exposure. The dragonfly is more of a gimmick. But for the price you can already recommend the part.
