The Very Best for chronic pain relief.
My first one lasted about 5 years. I Loved it.  I tried to replace it with other, cheaper versions but went back to this one as it is worth the extra money by far.  I love the power cord, the fact that it doesn't get hot or fly through batteries like other have.  Well constructed.  Easy to use. Just the right features.  If you have chronic pain, trust me, this is the one you want.
