I bought some this week, as it happens. Taking on board that the KAM ones were better I bought a KAM set. But, typically, the wrong one. I got the KAM PartyBar. As opposed to the KAM ParBar. What's a 'TY' between friends? About £100 and a few lumens less, it seems ... anyway, they work. I'll need to wait until next gig (10th Dec) to see if they work well enough on their own. I suspect they will be good enough, though, for the pubs/small clubs I play in.
