Hear From Other Grillers

Genesis SPX-435 Smart Gas Grill (Natural Gas) is rated 4.5 out of 5 by 626.
Rated 5 out of 5 by from SPX-435 new Grill Solid grill and good functionality. The digital “built” system for building the grill gives a real nice 3D view.
Date published: 2025-06-30
Rated 5 out of 5 by from Weber for Life Plenty of space for feeding a crowd or cooking large items like a Thanksgiving turkey. Heats up fast, has great temperature control, plus has a seer burner for extra high searing heat when needed. Love the WiFi connected sensors to let me know when the grill is heated up or when the meat is ready - wherever I am, so I don’t have to stay glued to the grill. I’ve used Weber for years. They last and last, and are well worth every penny. Can’t see switching to any other brand.

Rated 5 out of 5 by from Genesis SPX-435 Natural Gas Grill I have used Weber grills for over 30 year. In my opinion they are the best consumer grade grill for backyard cooks. I purchase this grill to replace my old (17 yrs) Weber Genesis grill which I rebuilt 3x with Weber parts. This new grill is fantastic, especially cooking with the rotisserie. The smart function works great with the meat prob and the searing is awesome. My only complaint functionally is the the ignitor for the side burner does not work and after tracing the wiring and reseating the connector I have not figured out why. That being said there are a lot of accessories you can add to this grill which really expands the utility of the unit. I recommend it highly.
