I keep a 10x20 canopy up in the backyard for additional shade by the pool. The Vevor cover lasts a season (8 months) before starting to shed a lot of white plastic particles and I remove it and put up a new one. I put a new one on in March or so and toss it in December. I am in Houston and we have brutal sun and humidity, as well as heavy rains. The bungee balls stay elastic for the time the tarp lasts. I keep buying this brand because of the price,
