We have had the 6 x 4 shed in this range for a couple of years, we have dismantled it and put it back up when we moved and it still looks as good as new and is as sturdy. So when we needed an extra shed at our new house we were pleased to be able to get a matching slightly bigger one. 
As with the last one the shed went together easily, the instructions were clear and my husband and son had it up in 2-3hours. They are now stood side by side and although one is more than 2 years older there is no discolouration, in fact you'd struggle to tell which is the new one!
