I was really fed up with my mat sliding across the carpet, so I ordered Anti Slip Mat Grips. I followed the instructions and stuck them to the under side of my mat and pressed firmly on to my carpet. I am very disappointed they did not make any difference at all in fact they made it worse. The mat started to flip over at the corners and when I caught my foot on it I trod on the little spikes which was quit painful. The little spikes seemed to get a better grip on my foot than they did my carpet. Also the adhesive lost it's stick after a week. I know they only cost £6.99 but I just can not be bothered to spend post and packing to send them back. As for getting them collected I just would not go there the delivery took days by some none English speaking delivery driver who kept getting lost. I should have learnt my lesson as I have ordered other goods in the past and they where not a lot of good either. So I will not be making any more purchases from Coopers.
