I have it for only 1 month but it endured a lot of rain in an outdoor space and it doesn't seem to have let any water through to the BBQ. Also, it endured a lot of wind and didn't suffer any damage. I didn't expect it, as other covers I had before were useless.

Coming back after 1 year to say that it was ruined by the sun, rain, and wind and it tore apart, it became useless. Unfortunately, the BBQ is very exposed, I use 2 covers, this one on the outside. No other cover lasted more than 6 months, it is definitely worth its money, I will buy this one again
