This battery grip is a super alternative product at an unbeatable price and highly recommended. The handle fits perfectly, is super processed and has all operating options that also offers the original grip of Canon. Personally, I think he is even better in your hand so you almost feel compelled only photos in portrait orientation shooting. :-) The batteries last even after the 2nd charge what they promise. Yesterday I shot about 400 photos, of which 50% with and 50% without flash, the camera in between often identified at / and the battery indicator jumped to the conclusion on 50% battery capacity in order. All in all, a wonderful addition to the camera, without making if you want to make time for a whole day photos worrying about the battery running. If it was not enough but once one has still the original battery and even if that should no longer suffice, you can provide through the mitgeliferten Adapter Camera with 6 AA batteries.
I was completely convinced of this product despite initial skepticism and it can only recommend any EOS450 owner!
