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.

Very nice and priced right
Size: 48 inch, Color: Heavy Duty-Black
Although this cover is slightly larger than my grill, it's heavy duty and should last a long time in the weather. Installing was a breeze, and the velcro straps help secure it in place better than my last one. This truly is a nice cover and appears to be able to withstand anything thrown at it. Nice product, 2 thumbs up!!

Too much material so that it gets stuck under wheels
Size: 58 inch, Color: Heavy Duty-Black
Very large grill cover, lightweight, but it covers my grill and since it is over-sized very easy to take off and put back on. My problem with it is it's got too much material so that if I have to move my grill away from the house to use, the material gets stuck under the wheels. I may have to re-hem it or send it back. Those with stationary grills won't have this problem.

Looks sharp, concert black, comfortable some stretch
Size: Medium, Color: Black
I bought this for my son to wear at his band concerts, and it’s been perfect. He’s about 5’8” and 155 lbs, and I got him a men’s medium—it fits really well with a comfortable, true-to-size feel.
The quality is excellent: soft, lightweight, and breathable, with just enough stretch so he has the flexibility he needs while playing trombone. It also looks really sharp on stage.
