I have had mine for about 7 or 8 months by now and until yesterday I have been EXTREMELY happy with it. It was a lot cheaper then the canon one plus it came with 2 batteries. I was assisting (and second shootering when I had time) a wedding yesterday and during the family portraits when I was changing batteries the little plastic latch snapped. The latch has to be push against the little button hat tells the camera it is able to turn on otherwise it will stay off. Luckily it was completely gone and I was able to wrap a rubber band around the body which help the latch down. RIGHT before the ceremony I was setting up to get the bride as she walks in and the rest of the latch broke off. I was freaking out trying to get it fixed but I wasnt able to. I had to try and jam my finger and press the tiny button to get the shot. Of course I didn;t have the cameras original battery door because I didnt think something like this could happen. I ended up not being able to shoot any of the dinner dancing or candids during the rest of the night which was disappointing. The grip comes with the AA battery holster and I managed to screw off my broken latch and replace it with the one that came on the AA holster. I have a feeling tho that will eventually break too and then my grip would basically be useless. I don't know if this is common but I am now ALWAYS going to keep the cameras battery door with me in case the grip fails and I would recommend everyone else does the same.
