I went to Calor because it was a name I could trust. The image appeared to have the regulator attached to the hose and the fitting the BBQ end. I, therefore, assumed it would be ready to connect to the BBQ and use straight away. This was not the case, the parts were all in a plastic bag with nothing attached. This is would not be a problem but there were no instructions. This made me really nervous - dealing with Propane gas and the dangers inherent in not getting it fitted correctly. So a quick search on YouTube pointed me vaguely in the right direction - though I was not sure if I was using the correct parts. By necessity, the parts did not easily fit into the hose as naturally dealing with gas there has to be a tight fit. I understand why the BBQ end parts were not all pre-assembled, as this depends on the BBQ connection, but surely the regulator should have been attached (as shown in the image). Notwithstanding this, the parts were good quality (hence 2 stars rather than 1) and a competent person, no doubt, would find it straightforward to fit.
