Summary

George Hotz received a $500 Dyson CameraJet toothbrush as a birthday gift and it broke within 30 seconds when the included mouth rinse leaked into the electronics compartment. He discovered this is a widespread issue affecting many users, with Dyson offering only a burdensome return process. He contrasts Dyson's apparent QA failure with comma.ai's rigorous hardware testing practice of stress-testing every device for 16 hours before shipping. He argues there is no excuse for a mature consumer electronics company to ship a liquid-handling device without testing it with liquid. He calls for a recall and direct resolution, not bureaucratic runaround.

Key Insight

A mature hardware company shipping a liquid-handling device without liquid-testing it reveals fundamental QA dysfunction — something comma.ai solved by stress-testing every unit before it ships.
