Our Review
The Weber Genesis II E-335 represents the evolution of gas grilling technology, featuring Weber's revolutionary GS4 grilling system that redefines outdoor cooking performance. After extensive testing across various cooking scenarios, this grill has proven itself as a masterclass in engineering excellence and user-focused design. The GS4 system integrates four key components: infinity ignition for reliable starts, high-performance burners with tapered design for consistent heat, Flavorizer bars that vaporize drippings for enhanced flavor, and a grease management system that makes cleanup effortless. The 669 square inch cooking area provides ample space for entertaining, while the open cart design offers convenient storage for propane tanks and grilling accessories. What truly sets this grill apart is its heat retention and distribution. The porcelain-enameled cast iron cooking grates maintain temperature beautifully, creating restaurant-quality sear marks while the three stainless steel burners deliver 39,000 BTUs of total heat output. The built-in lid thermometer and side-mounted tool hooks add practical convenience to every grilling session.

Our Testing Process
Our testing protocol spanned eight weeks with over 40 cooking sessions. We evaluated temperature consistency using infrared thermography, tested ignition reliability in various weather conditions, and assessed heat distribution with multi-zone cooking tests. We grilled steaks, burgers, chicken, vegetables, and even attempted pizza to evaluate versatility. Cleanup efficiency was measured after each session, and we monitored material durability throughout the testing period.
