Good quality, great price
Size: 72 Inch, Color: Black, Size: 72 Inch, Color: Black
Lovely cover and very well-made. I’m not using it for a grill. I am using it for my beach cruiser bike. I love the fact that it’s reflective fabric on the inside. It fits very well and it’s very lightweight and well maneuverable compared to the thicker fabrics that are sold out there. I highly recommend this item. I’ve only had it for a couple weeks, but so far very waterproof and doing the job. Easy to put on and remove.

Good quality, water resistant
Size: 52 inch, Color: Black
Feels thinner than the one I had before this which was the same company and model. Still good quality and value for the money. Fits well and looks good. Is water resistant and black is the true color. We’ll see how sturdy it is over the years.

Good cover for the price
Size: 58 inch, Color: Black
I’m very happy with this grill cover so far. It fit my grill really well without being too tight or loose. The material feels sturdy and weather-resistant, and it seems like it will hold up well over time. It was easy to put on and gives good coverage and protection. Definitely worth the purchase

Good quality for a great price!
Size: 52 inch, Color: Black
Very nice grill cover! I thought it was going to be a thin piece of plastic, but I was surprised when it came and it’s actually a substantially thick layered cover. The inside has a thermal layer I didn’t expect. Even the Velcro tabs on the sides are thick! I feel like I really got my moneys worth! I just have a regular gas grill that gets little use. I noticed this year there was rust on it in spots, so I thought a cover would help prevent any more rusting. I think this will definitely help my rust situation, plus it looks neater with a cover. Very happy with this purchase!

Great product
Size: 58 inch, Color: Black
This cover is excellent quality and fits my grill perfectly. The material feels durable, and it’s fully waterproof, which protects the non‑stainless steel parts from rain and moisture. Overall, it gives me great peace of mind knowing my grill is well protected.
