This Sunstone 28-inch grill is an absolute beast! The heavy-duty construction is immediately apparent, and it fit perfectly into my outdoor kitchen island. The burners heat up incredibly fast and evenly, making searing steaks a breeze. I'm genuinely impressed with the quality and performance.
I've been wanting a built-in grill for ages, and this Sunstone SUN3B did not disappoint. Installation was straightforward for my contractor, and the sleek design really elevates the look of my outdoor space. Cooking on it is a joy, everything comes out perfectly grilled.
Overall, this is a very solid 3-burner grill for the price. It heats up well and feels durable. My only minor complaint is that the igniters can be a little finicky sometimes, but once it's lit, it performs great. Still happy with the purchase for my backyard setup.
The Sunstone 28-inch grill was exactly what I needed for my new outdoor kitchen. It integrated seamlessly, and the build quality is evident. The three burners provide plenty of cooking power for family gatherings, though I wish there was a dedicated sear zone option. Still, a fantastic grill.
Wow, just wow! This Sunstone built-in grill is a game-changer for our outdoor entertaining. The consistent heat across all three burners means no more cold spots, and I've cooked everything from burgers to delicate fish with perfect results. It's truly a high-performance essential.
