Weber Genesis II S-435 REVIEW

weber natural gas grill cooking surface

The Weber Genesis II S-435 grill is a little different kind of beast. Not only is it cheaper than the Napoleon natural gas grill, but it also has a few distinctive features.

Well, S-435 is not exactly cheap, but it costs a few hundred dollars less than the Napoleon natural gas grill.

Perhaps the highlight of this model is the flavorizer bars. Designed by Weber back in the 1980s, these bars’ purpose is to catch drippings, vaporize them, and send them back to the food for extra flavor.

Apart from that, the S-435 grill is compatible with the Weber iGrill 3 app. This app can take readings from up to 4 meat probes and allows you to monitor the grilling process remotely from start to finish.

With that said, the app requires you to purchase the iGrill 3 device separately, and it costs about $100. It may be worth the money, but your budget needs to bigger to afford the grill AND the device.

The integrated sear station is also notable. It is designed to deliver heat to the searing rack quickly to give you those meat sear marks.

When it comes to the cooking capacity, the Genesis II S-435 natural gas grill isn’t too far off the Napoleon grill – it has a total cooking area of if 844 square inches, 646 in the primary rack and 198 in the warming rack. As you could have noticed, the primary rack in this unit is a little larger than in the Napoleon grill, which may matter to some people.

The number of primary burners in this grill is 4, with their heat output being 48,000 BTUs. Although this grill has no fancy features like infrared burners, its heat capacity should be enough for the size.

Like the Napoleon natural gas grill, the Weber S-435 grill has two side tables. The right table is again equipped with a side burner, but there are no integrated coolers in the other table. Still, you are getting ample tabletop space for food preparation, as well as a few utensil hooks.

We also like the oversized front wheels in the Weber grill. They should make this grill easier to move around than the Napoleon unit.

As for downsides, the S-435 grill has one – it’s pretty difficult to assemble. It comes with a lot of parts, but the manual at least seems decent enough to somewhat alleviate the challenging assembly.


  • Cooking area of 844 square inches.
  • 6 burners with 69,000BTU output.
  • Integrated side burner and sear station.
  • Extra flavor with flavorizer bars.
  • Side tables with tool hooks.
  • Compatible with the iGrill 3 app.


  • Difficult assembly.
