This Gelset, which can be used both for Canon and Yongnuo flashes leaves no wish unfulfilled. You can quickly and easily attach a gel before the flash and quickly correct the appropriate lighting conditions. The reason I did not award five stars is the rubber band was which supplied. It's too tight and it is accordingly difficult to push the tabs including the gel strips. I have this replaced by an ordinary household rubber and it works flawlessly and is much faster. The set is comes in a small bag, so the filter before the wrinkles are protected.
