Mine arrived a couple of days ago. Lovely bit of kit. It took 10 minutes to fit and it does exactly what it says on the tin.
Posted and delivered to the land of watches, chocolate and fiddly but useful knives. My only suggestion is that on international, non EU posting, please put 'replacement parts'. Smiling Swiss customs relieved me of the equivalent of a further 5 pounds plus the same again in postage 'customs handling fees'. Replacements are usually tax exempt and parts like this are generally not an issue. Still, great value compared to what I would pay here!
