Just recieved this - I'll update after having used for some time. But I must comment on the packaging: wow. The case just opened easily with a click, the sockets didn't fall all about as I raised the lid, and they snap out-and-in crisply. The sockets themselves have some kind of anti-corrosion coating, look superb and my first use of them seems to indicate they're superb.
