They look nice: as you say, far more compact than the more powerful versions available.
My frustrations with ADJ equivalent "micro" barrels is 1: the brightness isn't enough, but 2: the non-changeable gobos are often a bit too industrial looking. Whereas they look like a good selection of gobos.
If they were changeable gobos, I'd be buying a pair. Just a shame the changeable gobos never seem to appear on the cheaper fixtures :(
