if you want to know my opinion , I think that some persons involved in the rebreather market like to come in the home builder world and on the rebreathers forums criticise all they can criticise.

mabye is pvc dangerous, but this is the way that it is said that I dislike

they never say , hi guys just to let you know in our company we found out that pvc is bad try to find something else.

no they always say, building rebreather is a serious matter not a garage game on they other hand we can make good rebreather EC compliant bla bla bla.... heu how many people were killed by EC appouved rebreather ?

we are still waiting for the miraculous rebreather, for the technologic revolution.....
