What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Weber Slate 30" Rust-Resistant Griddle (1500014)
Only Engadget hands-on tested the exact 30-inch Weber Slate, praising edge-to-edge heat distribution, the rust-resistant cooktop that extends the cleanup window, and the modular Weber Works side table, while flagging cheap plastic wheels and that rust-resistant isn't rust-proof (small rust spots after 36h left dirty). Tom's Guide's tested review covers the larger 36-inch model, so it's excluded here; no other whitelisted tester reviewed this SKU. (1 sourced review, 1 lab-tested.)
Praised: Even, edge-to-edge heat distribution; Rust-resistant cooktop buys extra cleanup time; Modular Weber Works side table and accessories.
Flagged: Cheap-feeling plastic wheels/casters; Rust-resistant is not rust-proof (small rust spots after 36h left dirty); Cover's grippy interior catches on the side tables.
