dot bottles
no will will and cannot test dot bottles so dont but them a you cant get them tested and b not used in europe so your choicewill hpac or others test DOT bottles so that they are then Pi rated? just out of interest because one of my mates made the daft mistake of buying a ninja bottle from the US, and is now paying mega bucks (ontop of the money spent getting it here) to get it changed for a guerilla bottle.
