I am trying to register the warranty... haven't used the product yet, and I'm forced to give a review. You get a 3 for the annoyance factor. After I use it, I'm sure you'll be upgraded to a 4 or 5. Hope to be able to finish the warranty process.
I am 84 and at this age, we have struggles with balance becoming vulnerable to falling. I bought the Waver to improve my balance. I am getting stronger as I use it daily. A young man walked me to my car after church saying “You are getting stronger.” That made me happy that it was noticeable to others.
