First, I must say that I have not had to use the extinguisher! Well wrapped up, he came with me. When unpacking I had the inspection sticker in hand stick to one or to obtain attachment and should write the date. Also good I think that it is provided with a real Verblombung! The extinguisher has a good weight, had another 1kg extinguisher in the hands of definitely looked eating not so much! The holder for the extinguisher is robust and holds the extinguisher quite tightly enclosed, but you get him in an emergency still very fast out of the holder! Had the extinguisher installed at a stock car race in the interior, the holder has endured all shocks etc., the extinguisher has not come out of the bracket, I would say, therefore, passed endurance test !!! I had to use it unfortunately (in relation to the assessment) not yet, so I can not say as much about the functionality! So far, a top product, I trust that he keeps at a possible use also its promises so far !! That's why first 5 of 5 stars!
