Good light output from a small, light unit. However the build quality isn't great and in the past year I've had to repair 4/5 units (full disclosure - I don't flight case them, although they are kept in boxes). Most damage has come from moving the legs around (rubber washers break, threads wear). However, they are very cheap and there's a fair amount of DMX control available. They also look great and come with some useful built in colour chases and fades. The light output is nice and even, covers a decent area and there's very little fringing apparent (unless you put them right against a wall or something).
Cheap and cheerful, but be prepared to pamper them a bit.
