I have just put one of these lights over my Aquamedic Blenny last night, I won the light in a youtube comp and after playing with the settings and looking the light over I am pretty impressed. The android app is pretty easy to use and the build quality is good and it comes with a nice adjustable stand and hanging kit as well.
I will be getting a par meter in a few weeks so i can test the lights par and post up the numbers then but so far it looks like a nice light.
