Great base, easy to use with great online help, videos to make installation as quick as possible.
Ordered the size for my shed but due to metric / imperial sizing I have quite a few sections left over. These sections are in 0.5m and my 7″ shed was 2.04m so I didn’t install the last row and can use them elsewhere.
