As a rule when I'm working as a qualified electrician, I never buy cable (or other materials) from eBay when I'm working on a client's home as it's common to see sub-standard / fake items which could potentially be dangerous.
On this occasion I was working on a project for myself creating a new custom-made piece of machinery for the workshop and bought this moulded plug after looking at many others for sale here. I thoroughly checked it to make sure it was safe and I'm glad to say this is very good quality and I'm happy to use it myself.
