The delivery was as usual very quickly. Thanks to Amazon for this. At first I assumed that Meike is a German brand. Now Meike, was just obvious). The fact is that it is a Chinese brand and actually Meike says: D. Anyway. I unpacked the battery grip and a really unangenemer smell surprised me. Since I have however used immediately to handle, there was no time for airing. Its proximity to the nose when taking the first two days the smell was really really pushy and annoying awful. Now the handle smells absolutely neutral and I would not like to do without him. There are two devices available which can be inserted. One can be powered by batteries and the other with the commercial Canon batteries. So far there were no problems. Of course, the pushbuttons have a completely different feeling of pressure as the original buttons. They act even more like plastic. But the handle is not processed cheaply. But on the contrary. The original handle confusingly similar. Have fun with the handle.
