My 1st impressions after a few manipulations home and a day of fairly intensive shooting in the field, are very positive. Product of very good quality. Perfectly fits my brand new EOS 70D. The grip is really improved and extended range thanks to the 2 batteries supplied in the kit and the accessory (supplied) for 6 AA batteries. The materials are of good quality, the adhesion of the grip is very satisfactory (identical to the handle 70D) and the assembly is nickel. The small infrared remote control supplied is a small "plus" very nice. It works by pointing it at the IR receiver on the front of the grip. It remains to see how the product evolves over time. But for a price three times lower than the product of the Canon brand, the record is now very positive.
