The purpose of the design project has been to reconsider all the different ways of use people had of traditional massage guns existing on market. Our product, OPOVE APEX is simple to use with one or two hands. Furthermore, the 45 degree inclination of the handle confers a great grip, allowing users to relief upper back muscle-aches as well as pain of the lower back, arms and leg. The repartition of the weights is perfectly balance on the hand which actually makes the product feel way lighter than what it actually is.
