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.
