I bought the Reflex at a recent convention and love its power and versatility. It works as a video light and a flash, it is small, with a premium build. I will be testing it out in the studio soon.
What I would improve on is the usability. When holding it with the lens forward, I have adjust my thumb to press the small power button on the side. As someone who played video games since a youngling, it would be great to have a big central power button. Also, the light stand connector has an allen wrench with a small screw that could be easily lost. What if you had two screws on opposite sides to secure the connector in place? That way, there would only be two parts, the light and battery handle, that become one.
Another thing down the road would be to make an RGB version. You could get neutral, warm, and cool light and all the colors of the spectrum. This would make the Stella Pro a complete lighting setup the size of a speedlite.
The last thing would be if it came in a case with a hard shell. This is a very expensive and powerful light, so it should come with protection.
I love the power and function, but the user experience can be slightly improved for a truly interstellar (did you see what I did there :) ?) experience! You all have amazing customer service. Thank you!
