Mr. Shao Hui, the founder of REVOMAX and a former Intel Chinese engineer, discovered various bugs in the threaded lid during a trip, so he launched a crowdfunding campaign on kickstarter, the world's largest crowdfunding website, to make this cup without a threaded lid. out.

Because of the appearance of this cup, he once received a thank-you call from a special user. On the other end of the phone was a one-armed veteran who lost one arm in the Vietnam War explosion. He really liked the design of REVOMAX, which turns on and off in seconds and can be operated with one hand.

Although there are many cups on the market that can be used to drink water with one hand, more importantly, REVOMAX allows him to fill and pour water with one hand, which is something that other cups cannot do. Even if he lives alone, he can be relaxed and happy. Not dependent on others.

Usually, whether you are drinking or filling water, you only need to press the lock button in the middle, and then press the buttons on both sides at the same time to open the cup in one second, which is much faster than ordinary screw-top thermos cups.
