i first heard about whole body vibration machine from my chiropractor Dr.Daniel Turack. i used it at his office as part of my treatment plan. once i learned that i can buy my own, i immediately placed an order. our whole family is using the machine - from a newborn in my hands, to our 2, 4 and 6 yr old kids, mom and dad of course. i only wish we had more time in the day to use the machine! we dont have any medical conditions to specifically treat with the help of Hypervibe, but having a quick 5-10 min shake up in the morning or before bed time feels just so good! Delivery and customer support was exceptional. instructions, tutorials and videos are easy to understand and follow. we had some hiccups with the app where one specific tabata workout would freeze up the phone and turn off Hypervibe but i think it resolved itself with an update. and while one might not see visible results on the surface, benefits of this machine are tremendous. we've been using it at least 60 min every week for the past 6 month and feel great. Overall, well worth the investment. thank you!
