After I put it to the test, I was amazed at how well these lighting flashes worked for my photography projects. The dimmer switch makes it easy to find the perfect lighting for each shot and the option to switch between 3000K and 5000K is a game-changer. I`ve used many electronics flashes in the past, and these are easily some of the best. My only con is that they are a bit expensive compared to other options on the market, but for the quality and versatility they provide, it's worth every penny..
