I thought that the lock I bought was easy to purchase via the internet,it gave a very good description of the product which I think is important and delivery was quick and on time. After receiving the lock I was able to fit it without too much trouble although the instructions were very basic and if you were not use to doing a little diy you might struggle a bit. Overall I was very pleased with the product,it does the job I want it to do and I found it very good value for money which is one of the main reasons I choose this product.
