The CE thing is rubbish and means nothing. If you read the regulator manual for Scubapro you will note that CE compliance is invalidated for two people breathing the same 1st stage. In other works the standard UK recreational confiuguration of primary and octopus on a single 1st stage is outside CE compliance. If, therefore, you need to comply - say in a work situation like an instructor - the regulator should have only one 2nd stage. Instructors or other working divers therefore need to have H valve and two 1st stages. (Dual outlet tanks for instructors is law in France).
As for magazine tests... the problem is they tend to be on shiney paper which makes it useless for what it should be good for...
