With no prior knowledge or experience I decided to convert my 20 foot shed into a water catchment zone. Found Clear Amber online in a search and it was evident immediately that with the range of products and explanations and diagrams of what to get and how to install it, I could do this. I easily put my order together and unbelievably the order arrived THE NEXT DAY. It was so easy to put up and fits perfectly! I have an efficient and brilliant guttering system on my shed that looks great and I have plenty rain water for my garden. HIGHLY RECOMMEND!
