It's almost as if they got a load of stuff in and asked people to guess what it was for. Every reflector is a "spill kill" - except for the 120 degree wide angle, which probably is the closest they have to a spill kill...:-/
I have bought bits from them over the years - I like them most for wheels for your stands, and barn doors for small reflector dishes. They are ok - they stuff is cheap, but there's not a lot to go wrong with chunks of metal - not sure I'd buy a softbox from them. You also have to know what it is you are looking at before buying - because they don't
I looked at that spot projector too - it looks ok, but I couldn't figure out from the small picture what the gobo holder looks like. The diameter is much bigger than the Lightblaster, so it might make better use of the light from a studio head.
