With respect to the grip, the completion is identical to Canon camera. Plastic is strong and pleasant to touch. The grip lot bigger overall, but is very convenient for portrait mode shooting with the trigger button on the right place. It is perfect.
Regarding the two batteries, they are not fully charged when you unpack. So make sure to load completely to be able to judge. I have the opportunity to test the grip. I was able to film 5x 29 min. 49sec. (Box recording limit) before they let go. I was not expecting that at all! They work perfectly with the barrel loader.
In conclusion, this grip is a quality / price ratio. I recommend it to anyone who does not have the budget to take that of the Canon brand (170 anyway). I am completely satisfied!
