Pro:
-günstiger price compared to the original
-quality processing
-Druckpunkt The buttons (Zoom In / Out, etc.) clearly felt
-Goldkontakte
-Handling (Especially when using ext. Flash) greatly improves
Cons:
Shutter releases a little "spongy" when compared to trigger the 400D (I just got but after only 1 day accustomed)
So there is nothing (except the familiarization time) against Jenis battery grip! Would buy it again at any time!
