I bought a 'heavy duty' swing cover last year. It was used for 6 months as it went away during the autumn, winter and spring. Having been away I brought it out again about 4 weeks ago. The zipper pull broke off and then the whole thing ripped in a strong breeze this week. Inside there were cracks in the fabric all over. It cost £42.99 from what I thought was a reputable company but they don't want to know as they only guarantee the cover for 1 year. I suppose they expect me to buy a new one each year but in future I shall buy a cheaper one and throw it away at the end of summer. I shall certainly not use this company again.
