The SUN4B-IR is a solid grill, and the infrared burners get super hot for searing. Installation was straightforward for a built-in, but I wish the igniters felt a little more robust. Overall, it's a good addition to my outdoor kitchen, just not quite perfect.
I'm really impressed with the infrared burners on this Sunstone grill. It gets to temperature fast and gives a fantastic sear on steaks and burgers. The 34-inch size is perfect for my family, and it looks sharp built into the counter.
This Sunstone 4-burner infrared grill is an absolute beast! The natural gas hookup was simple, and the cooking performance is incredible – everything comes out perfectly. It's truly the centerpiece of my new outdoor kitchen, worth every penny.
As a contractor, I've installed a lot of outdoor grills, and the SUN4B-IR is a really good option for the price point. The build quality feels substantial, and my clients are always happy with the cooking results. It fits well into standard outdoor kitchen designs.
Wow, this Sunstone grill is fantastic! The infrared burners are a game-changer for searing, and the even heat distribution across all four burners is excellent. It was a breeze to install as a natural gas unit, and it looks incredibly sleek in my outdoor kitchen setup.
