No way!. Mighty Mug's patented Smartgrip, is an entirely new function. While Smartgrip does function similar to suction by trapping air - that's where the similarity ends. Unlike a suction cup. Mighty Mug does not require you to press it down to grip, or peel it off to lift. Simply set it down and it grips. Needs a sip? Lift it straight up and it lifts naturally. Sort of like a magic trick for your desk.
Also, Mighty Mug's Smartgrip will not wear out over time.
Mighty stays hot for an amazing 6 hours and cold for 24, so yeah, we got you covered there.
That means your drink will be hot/cold well into your day, ensuring you drink stays tasty.
We are so confident that you will absolutely love your Mighty Mug, that if for any reason you don't - send it back to us within 30 days, no questions asked for a full refund*
