I turned to this product because it also functions as telecomande for housing, which avoids to purchase (and carry) this accessory. The radio transmission is very good, I have so far missed any photos. The production is a little lightweight plastic but it is also not in the Chinese gadget that breaks after two weeks. And then to transport it, I always prefer it to larger, heavier-pocket wizards. I find the good ergonomics see very good. For example having two test buttons is very convenient by location and the position or placing its flash / box. The flash shoe on émeteur also allows uttiliser flash on the case; practice. Product supplied with numerous cables and adapters for compatibility with a flash meter or studio flashes. The battery life seems good, I have not worn those that were provided. Finally, I have not had a problem of inadvertently turning in my bag. I must clarify that I never stores the as-is into the bag I uttilise a Case originally planned for a microphone in which I put the emeteur, the receiver, the adapter for nikon telecomande, the PC adapter, a spare set of batteries and a sync cable 5m spare PC.
