Pattex No More Nails

Bougth the Pattex No More Nails that supposed to hold up to 80Kg. Disappointing product, and more upsetting is that the Salesman at Builders Amanzimtoti vouched for the product. The packaging says hold in place for 10 secs, I had to hold the multiplug adapters for 10 mins before it actually held - and an hour later it fell of the wall. Put on more tape and placed it back on the wall and found that it was on the fall this morning when I got in. I have literally used 3/4 of the roll.
