I'm really disappointed with the time of delivery because I needed it for a shoot for April 17.
For those who want to use with a Canon or Nikon case ... I suggest ordering one jack preferably "Towards 6.35 mm Stereo Female 3.5mm Stereo Jack Male adapter Chrome Pearl" Who is on sale too on Amazon for 1,60E only. Personally I use the Canon EOS 6OD case with Magic Lantern.
If the product works perfectly well. Very cheap and good quality sound. So I put 3 stars because delivery too long and lack of battery.
