Do what he is, very expensive but reliable. However, IR range is not always as stated :(

Expensive, compact & well.
Unfortunately, the battery is a genuine CS5R bes ******* "expensive" So when you think times just in Conrad to buy a new ... can this thing like to have 14 time pharmacy price. Dear same here also order from Amazon.

Otherwise Grundverabreitung is good, it seems a little shaky on my 6D but works well.

In IR (infrared) but you have to be that it already reached Outdoor times no less than by 5-6 meters range end in the clear. Depends entirely on the weather / sunlight. But in principle, I find it a worthwhile purchase for me.
