Just got this for Christmas! I've been wanting one! My friend has had one for a couple of years and has raved about it. So far for me, it been easy to use. The guide that comes with it is clear and easy to follow. I didn't know it had a lifetime warranty, which is cool! So far, 5 stars from me!
I bought this product to help with my husband's shaky legs and inability to stand up strawhen he walks. I have a sciatica that has my right leg feeling unstable so.eti.ed, so hope it helps ith that too.
