First, I was very impressed with the ease with which I was able to select the required replacement lock from your website, then I was delighted with the cost, the simplicity of the order process and the speed with which it was delivered. Because the selection had been so easy, fitting was very simple. I guess that it took me longer to find the screwdriver than to fit the new lock when I had found it! I was pleased with all aspects of this purchase and would definitely recommend you to a friend who was thinking of buying any security device
