1st one I bought blow up, but as been pointed out...human error!
The can was a bit hard to fit, & the catch/locking mechanism was a bit stiff, but with a bit of the arm muscle, & less of the muscle between the ears, I managed to get it all locked away & fired up
Boiled the billie, & left it running on low to keep the water warm for the stragglers. Mate asked eventually if we were all finished, & he walked over & turned it off. Took about 4-5 steps away from it & BANG
Luckily for him, the injury was having to admit he near had to change his pants!
I'd never used, or seen one used before, & who needs instructions right???
I hadn't turned the pot stand up the right way, so it had been stopping the cannister & mechanism from seating properly. We'd figured because of that, as my mate went to turn it off, some gas had escaped & been ignited just as the flame was going out.
Have never had, or seen one explode since.
So as already pointed out by others, if they're used properly, you shouldn't have any worries.
