There are multiple similar looking mini regulators available in Australia... That does not mean they are the same quality. All of ours are tested at the factory and again by us before being sent. Each one has a serial number lasered on it to track batches and has a 1.8k burst valve on the rear as a last-ditch safety precaution if something were to go drastically wrong. The copycat ones have neither of these so they have no way of tracking faults in batches and are unsafe in worst case scenarios. Ours are covered by a 1-year warranty (except if you screw in a gas source with the regulator turned on). Don't take our word for it, read our reviews vs other companies and make up your own mind.
