Yes, they are rather expensive, but nothing IMHO beats them, I first saw them a few years ago (the 222 type) in the hands of electricians working for musical events/stage settings, then I bought a set of 221 type and simply fell in love with them, they are very, very handy and safer (besides faster in installation) than both twist-ons (which are not very used here in Italy) and screw connectors which are normal here. Recently a reknown Italian manufacturer[0] started producing similar ones and they are getting more common.
