I bought this in late summer early fall of 2016. By early summer 2017 small tears were starting where cover meets poles in some areas. Patched these areas to prevent further tearing to no avail. Now February 2018 cover is just tearing all over. always kept the snow off so that isn't the reason. Fabric is just to cheap and maybe not UV rated. It seems for what these cost they should last longer than a year and a half. Should have put the money towards a wood structure. Replacement cover is to expensive and time consuming to replace every year or year and a half. Poor quality even for a temporary shelter.
