Prestige PRO 665 RSIB

The Prestige PRO 665 RSIB pairs 5 main burners with infrared side and rear rotisserie burners for 99,000 total BTU and roughly 1,010 sq in of cooking area.

$3,849Approx. MSRP

A great fit for someone who entertains often and wants a big, evenly-heating premium grill and is willing to pay for it, but it's overkill and overpriced for a casual weekend griller.

Pros

  • Very good to excellent heat evenness across the grates in lab testing
  • Sizzle Zone side burner gets a strong sear on steaks
  • Rotisserie burner and interior grill lighting praised by owners
  • Strong build quality felt immediately on handling
  • Loads of cooking room — 1010 sq in feeds a crowd

Watch-outs

  • Expensive, flagship-tier price
  • Large 7-burner unit needs significant patio/outdoor-kitchen space
  • A minority of owners report temperature-control quirks
  • Heavy (352 lb) — pick its spot and leave it

Known niggles

  • Isolated reports of trouble maintaining set temperature with controls feeling unintuitive
  • Rare reports of complete loss of power to the grill's electronics
