The 2-pin euro-adapter plugs are used even on some brand-name stuff, but I am pretty sure that by law they should be fitted already, and obviously not be wonky!

A few years ago I got a dirt cheap UPS from ebuyer and it came with an IEC mains lead with an unfused 3-pin plug that had far too little "surround" to be legal. It was recalled 6-9 months later due to an overheating issue, although I do wonder if it was due to the plug supplied.
