Just about the most useless thing I have every purchased.
I purchased a pack of 4 Mat Grips for £9.99. The grips are meant to grip the carpet over which a mat is placed one side of the grip adhering to the mat. They are made of not very hard plastic and the protusions (can't call them spikes) are blunt. They will get close to gripping any of the carpets or rugs that I have tried. They have obviously not been tested by the vendor and I am tempted to conclude that easylife is deliberately selling worthless products.
