I work 40+ hours a week on a computer and noticed my hands were tired and sore at weekends, and then I planned buy a massager to hopefully help with a pains and needles for relaxing my hands. After searching and comparing products on Amazon, I chose this hand massager as it has powerful function and goes on sale, which is a great price for all the features offered!I've been using it for a few days now. I love the best design which is cordless! It can do least 6 full 15 minute cycles before it needs to be charged again, however it does charge quickly. JUST NEED A FEW HOURS! I think this isn't too much inconvenience for me.At first, I started on the lowest massage intensity setting as it recommended until I got used to it and now use it on the mid pressure intensity setting. The massage combined with massage and heat functions,which provides a perfect 15 minute hand massage.The massager has three levels of heat functions and does work well. As it's not "hot" but warm, and produces enough heat to feel it through using it. Meanwhile, I also wear complimentary plastic glove to use it. It will bring a better experience.The machine is very sturdy, at the same time, the exterior and interior are wonderfully designed. It has rubber feet to be placed on a hard surface but works just as well while sitting on the couch balanced on my lap or a cushion.I'm quite satisfy this hand massager. I has been purchased a second one which will be presented to my mother.
