Review on Neewer Photographic 12-Piece Universal Flash Speedlite Color Filter Kit for Canon Nikon Sony Pentax Olympus Panasonic Camera Flash by Mark Clark

Works great Pros: Great variety. Full Coverage. Easy to stow away. Cons: Velcro backing doesn't stick and doesn't come off very well. I solved the problem by sewing it on. It can also be a bit difficult to get most of the gels into the storage space. I would recommend not removing them completely, but pulling them far enough that you get the gel you want.
