Weber Genesis S-435 Liquid Propane Gas Grill, Stainless Steel

TLDR Review: Weber Genesis S-435 Grill

Published: April 15th, 2026

Verdict

The Weber Genesis S-435 is a powerful, spacious, and well-built grill that performs excellently once assembled and running properly. Its quick heating, even temperature distribution, and premium features make it a top contender for serious grillers. However, potential buyers should be aware of ignition problems, build quality concerns like flimsy knobs and rust-prone parts, and the high price tag. If you value durability and consistent performance, consider whether the occasional assembly and maintenance issues are worth the investment, or explore other options like the <component-button-product identifierProduct="some-other-product-id">Weber Genesis II LX S-640</component-button-product> for potentially better longevity.
