Judging by the price of this cover, I assumed that it would be a substantial, heavy-duty one such as the green covers you can buy for barbecues and garden furniture. The picture on the website was so small, it was hard to tell what material the cover was made of. When it turned up, I was disappointed to find that it was just a plastic cover. Also, the drawstring doesn't keep the cover tight and snug all the way round the trampoline as it is hard to pull it tight; it is only efficient very near the pulling end. As the cover isn't that tight further along, the wind manages to get under it, and we now get leaves, etc. on the trampoline. Our previous blue cover with elastic ties all around was a much better fit and lasted several years at half the price...
