Early Feedback

What beta testers are saying

★★★★★

"We used to run out of gas at least twice a month. Since installing the sensor, we haven't run out once. The AI reminder is scarily accurate."

★★★★★

"The ordering feature alone is worth it. I placed my first order at 11pm and had gas delivered by 8am. Totally changed how I manage cooking fuel."

★★★★★

"Setup took literally three minutes. The gauge on the app is satisfying to look at and the alerts give us enough time to plan. Brilliant product."
