Review on Neewer Camera Flash Head Kit: Versatile Bracket, Filters, Honeycomb, 📸 and More - Compatible with Neewer Speedlites and Q3 AD200 Flash Strobe by Chip Palmer

Pieces snap together with magnets. Color gels are thick plastic, not thin acetate sheets. If you need to use acetate for color correction or similar you can cut and install - so you are not limited to the 4 colors included. The bracket should fit any flash with a rectangular bracket. I used to have to do something to work like this - convenient, useful, and fairly affordable.
