"This product was recommended by our local Police Officers following a break in at the property.
Simple to install and cut to size with a hacksaw. Easy to read instruction sheet. Clearly by the nature of the product care must be taken when handled. I used an inverted strip ie face to face to hold and position.
Fairly flexible product allows for a uneven fence / wall.
Screwfix were the only retailer locally that stocked these spikes."
