Hear From Other Grillers

Genesis SPX-435 Smart Gas Grill (Natural Gas) is rated 4.5 out of 5 by 586.
Rated 3 out of 5 by from Great grill, nightmare assembly Was very excited for this grill. When opened, it appeared a whole box for the side burner assembly was missing. I spent 3 weeks between customer service calls and waiting for shipping to get piece meal replacements, and was still waiting for assembly screws that NOBODY could identify. Still have not heard back from CS, had to purchase my own. Great grill otherwise, even heat distribution, and excellent quality construction overall.

Rated 3 out of 5 by from It's just ok this gas grill is ok. the electronic were hanging down; they must have not been connected adequately. the manual is not easy to follow. I'm having a hard time connecting the power cord to the unit. I was expecting more for a high priced grill.

Rated 5 out of 5 by from New SPX-435 Smart Grill Owner As always, an excellent product from Weber. I’m really enjoying the “Sear Zone” as it grills up steaks nicely. Still getting into the different grates you can use for the area and I like having options. The built in smart options are good and had no issues setting them up. My third Weber grill and I can’t imagine ever using another brand.
