Cover doesn’t blow off in high wind and maintains its form for excellent protectionGood qualityThis is an excellent, well made cover. The elastic bungee draw string around the base works very well. The cover beads and sheds water off well in the rain. I also like the air vent that allows the inside area to breathe, which would inhibit mold or mildew growth in humid environments. I don't need to worry about that too much in Phoenix, but the vent also works well by allowing air pressure to vent, keeping the wind from billowing the cover and trying to blow it off. My use for this cover is very non-traditional. I'm covering a plastic garden sink that hangs on my outside garage wall, exposed to the strong Arizona sun most of the afternoon. If not covered when not in use, the sun would have destroyed it within a few years. Keeping it covered has allowed it to remain like new for over 8 years so far, and this is only my second cover. The 24" square cover fits over my 24" wide sink like a perfect glove and the elastic holds it nicely in place.I was surprised with the quality, strength and craftsmenship that went into this cover. It had that heavier feel right from the box and when I put it on the firepit, it actually stayed in place and I could tug on it to position it and secure it and I didn't have to worry about the corners or end ripping out. It is made with strong use intended. I had a bit of a problem determining how all the fastening straps hooked up but I eventually got there. The drawstrings on the bottom of the cover are excellent and provide added security as to not blow off or someone coming along and doing a "quick-grab" to walk off with it, but that will not happen. Since our first cover (not from CoverMates) shredded like a paper bag after a couple of years, I will be anxious to see the life of this cover - I expect much longer.The cover ordered was the one suggested by the seller.. too big for my fire pit. Covers well but looks a bit saggy.I've only had the cover a week so I can't say how long it will hold up under the changing seasons. But I can say that it is of a somewhat sturdy material, a little rubbery feel rather than canvas-like. I like that it has elastic at the bottom so it hugs the firepit instead of just hanging, and it has vents which helps prevent the moisture collecting under the cover. It also fit perfectly. So far, so good.Get this. I’ve had multiple fire place covers and all of them have flown off my roof and ended up god knows where. This is good quality, easy to put on, and I love the tightner tab. Makes it easy to tighten and it STAYS.Our firepit measured 30x30 and even though the cover measured that size it was still a VERY tight fit. My husband and I carefully put the cover on and carefully take it off when using it as to not tear it at the corners. Had I known it would be this tight getting it on and off I would have tried to order a slightly larger dimension as it doesn't completely pull down snug at the corners. While it is on though it keeps the firepit very dry during any rainstorms, is very well made and will not come off during high winds. Even with it's overly tight fit we've been satisfied with it.
