Should have done some more research but was looking for additional power supply for HP laptop and site seemed ok. Product not genuine HP as specified -no surprise I suppose. Of more concern is that the adapter runs at a temperature that is almost too hot to touch and is a serious concern in terms of fire risk! UK plug is compact but I read on another review that it doesn't contain a fuse -no sign unless it is moulded into the plug during manufacture. Overall will be throwing this away and buying from HP direct... suggest you stay away this company is a rip off!
