Oh my aching back
Was introduced to this cane recently and had to have one!  It works as well as advertised and I should probably give it 5 stars.  Helped some back muscles that sent me to the Urgent Care two days in a row.  Wish I had it prior to those visits and i might have forgone chemical treatments (pills).  Highly recommend if you have muscle aches and pains.  The manual is comprehensive and very detailed.  The instructions that came with the cane are a little lacking.  Have yet to view the DVD.
Rating: 4 stars
