I absolutely love this rapid filter system, this is a MUST for any hybrid shooter!
The build quality is excellent, very strong, very sturdy, the threads are super smooth and the hinge is tank-like.
I can't count how many filters I've scratched and how many shots I've missed because I didn't have this awesome gadget! I highly recommend it to anyone who uses filters to shoot with to create cinematic looking footage!
