I’m curious to know what makes this safer? Are our regular steel cylinders unsafe or did not go thru certification and testing?

They look shiny new and all but I’m skeptical about this tech?

I managed to get one from an agent from a neighbouring 'territory'.

A bit heavier than I expect at full tank. I can just about carry it with one hand to the kitchen. Wife can just lift it, cant carry.
And the tank is 'fatter' but shorter.

Where I live gas delivery is unreliable. So will use this as spare tank and for the dapur goreng2 outside, since it is rust resistant.

Gas price is as standard when exchange empty tank, i was told. The first downpayment is double that of normal steel tank, one off. but delivery charge is bit expensive though. Maybe bcos quite far distance in my case.
