Vibrating Back Support

I have been using this back support for months now. I only use it in the car because it only has a car charger. You can stick this in your work chair if you wish. I love the vibration. Only use it for around 15minutes and then turn it off for a bit. If you have lower back pain, the vibration helps to disrupt pain signals that your brain sends to your body, which can alleviate these symptoms and increase your comfort. There are 2 settings on this back support. High and low. The device is somewhat noisy. I only use the vibration on the high setting because the low setting is too soft for me.
