I have this product for the holidays Switzerland bought to avoid having to constantly change the batteries. It arrived on time at home and also sufficiently packed shockproof.
The box of the product looks almost noble very nice and for this price range. The delivery was the advertised wireless remote as a gift.
For product: processing solid, material good grip, smell strongly of rubber and plastic. Delivered 2 battery carriage. A sled for 2x standard batteries and a carriage for R6 batteries / accumulators. This is very practical as a replacement.
I am completely satisfied. Let's see what the long-term test says. The original Canon replaced it however to 95%. If it would not stink so.
Addendum: To note here is, should take place once a sensor cleaning, this battery grip is recognized by no one as Canon original and thus allows the blades to the sensor cover does not open. So disassemble, original Canon battery clean and close the battery ceiling of the battery compartment.
