OKJ 16' x 20' Sand Beige Sun Shade Sail Rectangle Canopy Awning Fabric Cloth Screen - UV Block UV Resistant Heavy Duty Commercial Grade - Outdoor Patio Carport (300x300CM)

The corners are strong and seem to hold up well however the material of the main sail sags very badly. I have several of these that all went up within a month of each other and they are now of no use. The material has sagged at least 50cm downwards. The one above my car had to be removed as it was touching the paintwork after just 2 weeks. The others can no longer wlbe walked under without touching your head. And, before I am told to tighten them, they are tight. I would have to move the wall brackets and re-drill more holes in the walls. OK for a temporary fix to a problem but not more than a mo th or two. Shame as they seem well made otherwise.

The quality of the sail is very poor, the material started to disintegrate and ripped all the way along one edge just after four months. Unbelievable to learn that it cannot be returned. It is shocking that Amazon offers such a poor consumer protection. Do not buy this product, it is a complete waste of money. Do not buy through Amazon if you care about a proper warranty.
