Since the 1980s, Genesis has been one of the most popular grills in the USA, appearing in backyards coast to BBQ coast. The Weber Genesis II E-310 3-Burner Gas Grill features Weber’s new GS4 grilling system, consisting of their Infiniti Ignition with an impressive ten year warranty, tapered-quadrangle shaped burners to replace tube burners, stainless steel flavorizer bars and a new grease management system located under the center of the cast aluminum fire box. A slide out tray funnels gunk into a disposable aluminum pan for easy clean up. Grates are porcelain enameled cast iron.

Weber rolled out the Genesis II line in 2017. We were among many disappointed. But an all new, much improved line of Genesis II came out in 2019. We’re calling the new models Genesis II 2.0. A member of our Pitmaster Club had a good question, “How do I know I’m getting the revised Genesis II?”. An obvious sign is sear burners. The previous Genesis II line didn’t have any models with sear burner. Model numbers 315, 3225, 335 and 435 are new for 2019. Lastly, per Weber, serial numbers on the 2019 models start with AE or GU.

We tested the Genesis II E-335 which is the same as this model, but includes a few nice additional features like an enclosed cart and sear burner. Click here for our detailed review. Many gas grills cannot effectively produce intense searing temps and need additional sear burners to get that truly mouth watering steakhouse sizzle. Though we found the Genesis II 13,000 BTU stainless steel main burners had an exceptional temperature range capable of reaching 680°F, the additional 9,000 BTU sear burner on the E-335 goosed temps over 800°F and left no doubt about the searing performance..

iGrill3 Digital Thermometer

Our main complaint for just about every grill is the obligatory, built-in heat estimator in the hood. These 19th century gauges placed up high in the lid can be off by 50 to 100 degrees from the actual cooking temp. Since we cook down on the grates, it’s always better to use a modern, digital thermometer and position a temperature probe at the cooking surface. Click here to learn about the importance of digital thermometers.

With their acquisition of iGrill Digital Thermometers, Weber is addressing this issue. Genesis II is “iGrill3 Ready”. It has a mounting place on the right side shelf for an optional iGrill 3 digital thermometer. It comes with two temperature probes and has inputs for two more. Download Weber’s free, user friendly app to monitor temperature(s), set timers and alarms, check LP tank level and more.

Our Review

This Bluetooth device enables you to clip a digital probe on the grate to dial up the correct cooking temp, and poke another one in your food to monitor internal meat temp. We tested the iGrill3 readings with our Gold Medal Award Winning Fireboard Digital Thermometer and they were spot on. The convenience of an accurate, built-in digital thermometer is well worth the additional expense, particularly if you don’t already have a digital thermometer. Check out iGrill3 on Amazon. Here’s a brief video from Weber about iGrill3 installation and use.

About the Weber Genesis II E-310

Weber Genesis II E-310 has an open cart with left and right side shelves an LP tank concealer on the right. Tool hooks are built-into the side shelves and the LP models also include Weber’s “Precision Fuel Gauge” which measures the LP tank weight and shows your approximate fuel level. There are two locking casters on the left and two large fixed wheels on the right.

Natural gas models are available, but no conversion kits, so decide before you buy. The Genesis II lineup is available in three and four burner configurations, for liquid propane or natural gas, with or without side burners and sear burners, and your choice of an open or enclosed cart. Below is the Genesis II E-410 4-Burner Natural Gas version.

4-Burner Gas Grill with a black lid, shiny front and shiny shelves on each side, mounted on four heavy legs with four wheels and a shelf on the bottom.

Warranty

Genesis II has a bumper to bumper 10 year limited warranty on all parts.

Weber-Stephen

Weber-Stephen is one of the oldest and most respected manufacturers of BBQ equipment and related accessories in the world. Weber grills and smokers cook beautifully and have great features that are clever, effective and easy to use. As popularity and demand for BBQ gear grows worldwide, Weber continues to earn their long standing reputation for quality, durability and outstanding customer service and support, (7 days a week from 7am to 8pm CST), in an increasingly competitive environment. Even in this crowded marketplace, many consumers are still willing to pay more for the Weber name and they are rarely disappointed. They make a variety of cookers and smokers. Their iconic black charcoal kettles are known throughout the world. Indeed Weber is expanding globally.

Weber-Stephen was family owned since it was founded in 1952 by George Stephen. At the end of 2010 the Stephen family sold a majority stake to Chicago investment group BDT Capital Partners. In 2012, Weber settled a class action suit out of court regarding their use of the phrase, “Made in USA”. Weber previously qualified the “Made in USA” statement by specifying their products are assembled in the USA with some components that are sourced globally. Here is an excerpt from Weber’s statement “Weber believes that because all Weber grills and the disputed accessories are designed and engineered in the USA, and all grills save for one line [Spirit]* are manufactured and assembled in the USA using component parts primarily made in the USA, it did nothing wrong and therefore has valid defenses to plaintiff’s claims. The court has not held a trial or ruled in favor of either party on any disputed issues. Weber and the plaintiff have agreed to settle the matter to avoid the costs of continued litigation.” As a result of this suit, Weber can no longer claim to be made in America.

Since then Weber, like many others, has outsourced manufacturing of more product lines. Things change, but we believe Weber’s commitment to quality and innovation has not.

The biggest barrier for many folks is price. Webers are not cheap, but when you consider that they last decades, the price is easy to justify. Many some cheap grills fall apart after three years or so.

Our main complaint: All Webers have the obligatory bi-metal dial thermometer in the hood that gives you a ballpark reading of what the temperature is high above the meat. Since we cook on the grates, though, it’s always better to bring your own digital thermometer and place a probe there. It appears this is beginning to change as Weber enters a new era of digital technology and software based products.
