I’ve had excruciating back pain for months. I could barely lift my leg or fully bend down, I got the Rumble Plus 4D and I have been using it for 4 days and my back has felt so much better, my back pain is almost gone.
Four minutes is all it takes to not be sore and stiff in mornings. It definitely helps me get rid of the bound muscle and sciatica pain. I love it and would absolutely buy it again.
