I have tried various machines for your back, but they could never do the shoulder and neck area very well,
this is a very good machine for the neck and sholder area, I find 10 min in the morning and 10 min after
a hot shower at night works best, its not a cure but keeps the neck and sholder pain at bay.
It has a hard kick and when I was looking to purchase a new machine various reviews from women said it was a bit
to hard for them, this can be the case it seem to work best at a higher level which suit me. A very good product for the money Though I am not sure how it will last on the long term use. I am thinking of buying another to keep at my place of work, as i am transporting mine between work and home. I also recently popped a muscle in my shoulder area and could breathe deeply, I used the machine and within the week it was better, which would have been the time it takes to get an appointment with a physio.
