How fragile is the solar vacuum tube?


Our vacuum tubes are make of durable laboratory grade borosilicate glass, designed to live for decades on a rooftop. They are extremely resistant to thermal shock and impact, but may rupture if if stressed enough (i.e. dropped from 5 feet onto concrete.). For that reason, all GoSun Sports and Grills come with a One Year No-Questions-Asked Warranty on their vacuum cooking chamber so that you can cook and travel with confidence.
