I have long wondered whether I need a battery grip. After a friend had bought this grip and I could try it, I also ordered him. When unpacking, I was thrilled - everything was as described in the offer. The handle fits seamlessly on the Canon 600D to, unpleasant odors, as sometimes described in reviews, I could not tell. Short recharge the batteries and then it went off. Alone handling the camera has improved enormously through the handle. With a 18-135 lens or the 70-300 tele holding the camera is much easier - not because of the weight, but because of better distribution of weight. Very relief are also the additional controls for vertical shooting. The infrared trigger also works flawlessly. With the battery grip is the next holiday and much photo fun no more obstacles!
