Worth every single cent. I unfortunately suffer with permanent nerve damage from my lower back and down both legs. The pain I have pretty much leaves me immobile. I started going to a pain management centre that focuses mainly on laser therapy. One day I noticed these hand held machines at the front desk and purchased one straight away. What an unbelievable difference this has made in my life. Unfortunately for the pain management centre I no longer go there as this device has me covered. I've gone from immobile to being able to walk around the house unaided. It also gives me confidence to go up the street to complete my shopping tasks when need be. Bottom line is, before this device I was honestly 90% immobile, now I'm able to complete tasks that I thought were long behind me.
