Originally, I never wanted a BG since me already so well is the EOS 70D in hand. But since I was the desire then eventually getting bigger also like taking pictures on end. The original was me but too expensive so I ventured to many positive reviews here on the good piece.
Processing: You can tell immediately that this is not here to the original battery grip. The buttons wiggle a little and take not so high like the camera itself. Still far from cheap scrap it appears to be very robust!
Function: Functionally, everything as it should. In the pictures not seen, there is also the focus point selection button next to the shutter release button. All keys have the right features and it is like having the camera "richtigrum" in his hand. The edgewise photography is so much more fun and you do not tire easily. The only drawback, but that is the nature of the battery handles, one can hardly at the preview button. I use it myself but hardly when they often need have to have his finger acrobat!
A cup for 6 AA batteries / batteries is also at times if you should come into power needs.
Batteries: Hard to believe but in the price are 2 LP-E6 replica batteries. Contrary to another review here can my original 70D charger to charge them easily. For durability I can make no statement but so far I have shot about 400 photos with it and they are both at 90%. I'm about the battery update as soon as I know more here.
Infrared remote control: As a little gimmick is an infrared remote control at. This is compared to the original quite large and, unfortunately, does not have the function of time delay trigger 2 seconds. Otherwise it works as it should. So can we use as a backup timer!
Conclusion: You get offered a lot for the money here. If you can live with the slightly worse processing and haptics gets here a fully functional battery grip for EOS 70D his!
Edit: After 3 charges the batteries I have to say they are from a performance point already well below the original Canon LP-E6. I would estimate about 60% if not even less. So to get together with the two barely more than an original battery. But you can also load the original in the battery grip and then has still spare batteries at a favorable price.
