Everything fits perfectly into one another, push buttons, triggers and the wheel feel exactly like the on the Cam.
- Mechanically so far I could not detect any shortcomings in daily operations.
- Odor nuisance, as one of my previous reviewers complained, were fortunately not in front of my grasp.
- Both bays (one for 2 batteries, one for 6 batteries) also perfectly (with the old for the EOS 400 were better).
Have the part now about three months and about 4,000 trips on the Cam and still is - almost - everything absolutely perfect. Because what one might complain a bit is the fact that now already lose the word "OFF" and two pictograms (sensor selection and exposure correction) to color. At the Cam, I can not find this development absolutely !!! not to the old handle (also commercially available) for the EOS 400 (and after nearly 3 years and the 20,000 photos). Therefore, only four stars
I would today still draw back to this battery grip, because simply I do not see before the price difference for the Canon and I'd rather save the money and invest in original Canon lenses L series, because I know I have what it when genuine Canon is on it ( added, because I still have a lot of Battery Grips buy until I have a lens together).
I hope I could help
Greeting
Ralf
