Cadac - Safari Chef

I have bought a Cadac Safari Chef 6544F (08) a few years ago and because I liked it and thought it was great. But you don't pick up if there is a problem immediately. Firstly, the High pressure pipe with connection(connects with the big gas bottles) you struggle to get hold of in the first place. Then, the connection directly connected to the stove get so warm that the high pressure pipe goes of. Eventually when you get to shop you hear that you are not the only one with a problem like that. The other problem is, the flame. You think that the flame will come out the way it should, but it doesn't. It will burn stronger to the one side that the other side. Now, we did an experiment our self's at home to see why is it burning stronger to the one side and we ended getting to see that the Jet 0.25 is where the problem is. Cadac manufacture the Jet's hole in particular skew but they don't pick it up. I was told that they test each and every one of them and that it is all good. No, it is not ok. Replaced the Jet already and the burner and it still gives the same problem. Cadac must take this serious and correct the problem ASAP. Makes me wonder about their other products.
