Genesis

The Weber Genesis gas grill is the dominant subject in this corpus, and the community overwhelmingly considers it a BIFL product — with many users reporting 15–25+ years of reliable use with only minor part replacements. Mercer Genesis knives and the Genesis luxury car brand also receive favorable mentions, though with some caveats. There is a notable concern that newer Weber Genesis models (Genesis II and recent series) represent a step down in quality compared to older units from the 1990s and early 2000s.

Older Weber Genesis grills (pre-2010s, especially 1990s–2000s models) are genuinely BIFL classics with decades of proven durability, but quality concerns about newer Genesis II and post-acquisition models mean buyers should research production era carefully or seek out quality used units.

The Weber Genesis is praised for its tank-like build quality, longevity measured in decades, and Weber's excellent parts availability and customer service. Older models in particular are regarded as virtually indestructible and easy to rebuild.

• Many users report 15–26+ years of continuous use
• Weber parts remain available and affordable for older models
• Weber customer service known to replace parts under warranty generously
• Used Genesis grills frequently found cheaply and easily restored
• Capable of reaching high temperatures even in cold weather
• Mercer Genesis knives praised as high quality at an affordable price

The most consistent criticism is that newer Weber Genesis models (Genesis II and post-private-equity acquisition) feel noticeably cheaper than older ones, with rust issues and quality control problems. Flavorizer bars need periodic replacement, and some users report frame rusting within a few years on newer units.

• Newer Genesis II models widely seen as lower quality than originals
• Some users report significant rust on stand and body within 5–8 years
• Flavorizer bars may need replacement every 1–3 years
• Genesis 400-series reported to have igniter and fit-and-finish issues
• Genesis luxury car high-mileage reliability questioned by at least one owner

One user described assembling their Weber Genesis and realizing why it was superior — the base was built like a car engine, with thick metal rather than the thin sheet metal found in other grills.

A user bought a two-burner Genesis used from a food truck after 15 years of commercial service, ran it themselves for another 8 years, and still couldn't bring themselves to replace it.

Someone noted that Genesis models from roughly 2003–2006 were bombproof — one winner of a Genesis Platinum used it weekly for 15 years through all seasons and replaced zero parts before selling it for $500.

Multiple users echoed a concern that after Weber was acquired by private equity and moved production, the new Genesis line lost the durability that made the originals legendary, with at least one person saying current models aren't half as durable.
