Hello, Item received quickly enough - After unpacking, according to the subject on the site, but some difficulties using from the start - battery check, it seems what is good, but it took some manipulation before the shutter is working properly ( namely, commissioning and delivery of the battery, battery check, etc ...) but after these manipulations miracle .... more .... no problem for more worries! in my opinion whim of the battery during transport! otherwise nothing to say Good quality overall - recommended
