I absolutely agree with Justins comments, I have tried and tested many companies mugs as we all do probably looking only at the price. For some time now I have have stuck to the BMS for consistency, they have a very good coating (unlike some) and the sides seem to be more straight (this is something which has caused me endless problems and waste) so i'd rather be safe for the sake of a few extra pennies. And as Martin has stated they come individually wrapped so I have never had a breakage.
