"I was installing a ring and some lighting circuits; and this provides good protection. The only issue is you have to buy wall pins to fix them as anything else (electric pinner) just shatters them. Drilling and screwing takes to long. Hammering in wall pins is about the best.
Protection wise it will not stop you accidentaly drilling the cable or a nail putting a picture up but it should give you an indication something is there before you go too far."
