Update:
I bought this product, and the one I got is completely unsafe.
While I was using it, the stem pressure pushed the nozzle attachment off the hand held bit, shooting boiling steam out (beside where my hand was), and shooting the nozzle extension off.
There is supposed to be a click in join that prevents this from happening.
I have informed the distributor, who are going to feed back to the manufacturer.
In my opinion, this is a serious design fault, which could cause serious injury.
It is possible that this was a one off fault in the product I bought, but given the potential for harm, this should not have passed quality control.
I am very unimpressed.
