Right, which is why I like AirGas. They take your old bottle and they inspect/test it before filling and giving to the next customer. Other places wanted me to send it off somewhere for inspection, pay the fee, and then bring it back for them to fill. Just saves time and money with AirGas.Seems like it would be a good idea to have a bottle holding explosive gas under pressure to be inspected periodically....but that's just me.
