Have used this for several days as a beginner and the swelling has gone down considerably already. I use it twice a day for 15 minutes each and increase the vibration each time. Will be going to next level of standing with use. My balance has improved also.
I will need to use the product before I can give an actual review. So far, it is sturdy and looks to be well made. Did a quick 5 minutes to get used to it. Relaxing.
