Great light, compact, integrated battery, excellent colour balance. The core things you want this light to do, it does very well.
A couple of niggles for a light at this price point...The whole outer housing is wobbly. While it's great you can swap the standard LED out for a tungsten-balanced one, the overall feeling is that the outer shell is poor quality. The way it locks into place (with the crappy sliding plastic knob), lacks precision and robustness. The lugs for attaching modifiers are also flimsy, especially the one that flexes to allow mods to be locked in. It does not fill me with confidence that it's going to survive extensive use, plus it's fiddly to dis-engage any attached modifier. Lastly, the power adapter. Seriously, that thing needs a re-design, it is massive and heavy. As the light only has 50 mins of battery at full power, you're gonna need to lug that big old brick to any longer shoots, basically almost doubling the overall weight of taking the light on any travels. As it has a proprietary connector, you have no choice but the use it. I would reduce the size of the brick, and introduce a more standard cable connector point to the light.
