The Frio clip is expensive, but it's worth every cent. Nothing holds your flash as tight and secure on a tripod or light stand than this puppy. The speed lights are easy to mount and easy to take off. But they don't come off, unless you want them to. No ifs or buts about it. I have 4 of them, and I never want to miss a single one. If you ever had a light crashing to the floor, you will want one of these.
