"The product supplied is quite different to the picture on-line and in the catalogue. What's given is an open square plate into which fits an F type socket module together with a separate blanking plate. You need both to fill up the square opening. Although this was a surprise it actually does the job well and you can put in a UHF co-axial socket instead of the blanking plate if you wish (at more than twice the price of this) to get both into one socket."
"This is a very poor product indeed. It is made up of three strips of clipped in plastic, with the middle part containing the f type worm. It is not one piece of plastic with a hole containing the f type. Crabtree electrical stuff is usually spot on. Not this time. Avoid."
