For this price, the processing could have been better! Delivered they were like Amazon usual 2 days upon order and I have to say. They do what they want and the distance is really far through walls at long range, it works very well but I must say that from the different recording modes is very very easy the switch and a bit of tact custom adjust it. What important to know is that you can set on the remote control all the modes can be made only by the fernbeding I place for example in the reienaufnahme mode this is not switched on the camera but it will only repeatedly sent a photo signal to the camera, the means you do not so fast photo series as they would if they had it switched on the camera so that it works with the Reienaufnahmen you have to make on the remote control bulb and then on the camera to photo series he shoots durable photos up to it again off. All in all, I will keep the product even if I find that it for this price has not a very good processing and the switching function in the various modes something works differently than you would expect when buying. That is why "only" 3 stars.
