Very hard to fix head angle securely. Mating surface is wide and flat, hard to apply enough pressure with hand. It should have been designed with spherical mating surfaces. Also, it is a very heavy torch. But I like the swivel neck, it is a useful design. Details should be improved.
The torch is leaking gas under the swivel neck. Because o-ring under the neck is sitting too high, it doesn't seal properly. Removing the neck and grinding about 1 mm at the bottom has solved this problem.
Item safely arrived. Recomanded.
