I am reasonably good and experienced at diy, but I hate anything to do with electrics, so wishing to install a water feature and other powered items in my garden I purchased this product. The product and the clear diagrams and instructions make it incredibly straightforward to install the necessary equipment in working order and to accepted standards.
Would have given it 5 stars but for 2 small niggles. Firstly although the instructions are clear, it is not as easy to fit the wire for the external item of equipment to the switchbox as they would have you believe, and I am sure the design could be improved in this respect. Secondly with regard to the screws supplied for fitting the adaptors and back plate, in my particular set one was missing and another had a head with a spigot which prevented the ingress of a screwdriver. This was not a problem for me as I had suitable spares to hand and did not raise an issue with the supplier or manufacturer.
Overall though a good product for the electrically challenged such as myself!
