In this overview post, we detail our rigorous testing protocols, including “torture tests” surpassing three million cycles. By subjecting components like suitcases, handles, and valves to extreme stress and heat, we identify failures early, achieving a 0.3% annual repair rate and ensuring professional-grade reliability for every machine.

In this post, we describe a custom jig developed to ensure every portafilter locks in perfect visual symmetry. By using torque-limited testing and specific spacers, we eliminate sub-millimeter manufacturing variances. This rigorous quality control ensures a consistent, premium feel across all machines while reducing manual rework during assembly.

To ensure perfect visual alignment, we developed a specialized jig that tests portafilter locking symmetry. By using torque-limited wrenches and precision spacers, we calibrate every group head to overcome sub-millimeter manufacturing variances. This obsessive quality control eliminates handle misalignment, ensuring a consistent, premium feel for every Decent owner.
Source: The sniff test
We perform a "sniff test" on every heater batch to eliminate unpleasant plastic odors. By identifying unapproved supplier components and implementing a multi-day "burn-in" process, we ensure your machine remains scent-neutral. This obsessive sensory check prevents chemical taints from reaching your kitchen or affecting your coffee.
Source: Torture testing our new portafilter handles
We've upgraded our standard portafilter handles to solid vinyl for better durability and feel. Through rigorous "torture testing," we identified a structural weakness in early samples and fixed it by sinking the connecting bolts deeper. These reinforced resin handles are now standard on our black machines.

We've redesigned our custom suitcase to enhance protection and portability. Key upgrades include removable wheels to reduce shipping damage and costs, riveted corner protectors, and a top-opening design for easier packing with dense foam. This collaboration with high-end manufacturers ensures our machines travel safely in a premium, durable case.

We put our V2 suitcase through an extreme "Teddy Challenge," featuring team member Teddy throwing a fully loaded machine to simulate baggage handler abuse. By jumping on and hurling the case, we proved the new high-density foam and reinforced corners perfectly protect the DE1's precision internals from heavy impact.

We perform exhaustive MTBF testing, running over 3 million stress cycles across our machines. By pushing components to their breaking point, we've refined everything from valve timings to manifold materials. This obsessive R&D ensures a remarkably low 0.3% annual repair rate, proving our machines' long-term professional reliability.
