No, I am not having it!
A good chunk of wood behind the insulation and decent fat screws know one will know. Or at least good decent plugs that can take the weight and pull.
I have been stung by BT in the past so sod em! and as for those bleeding sat dishes! Snapped one this week and it caused mayhem. A family having to go without Sky tv for 1 night, ever been there? They turn from nice customers to nasty buggers!
Now I am collecting a range of those flimsy plastic brackets, don't want this hassle again!
