Finally got a good test and proof this worked!
I was sleeping and somehow I got a nasty sprain on my side here really. I tried ice just made it hurt more. Then I remembered I had this little item. Also before I finish the story I thought it was cool they ship with some power. So if you needed instantly you would be able to. So I grabbed this turned on selected 2 wavelength hit start after only 1 minute of use the pain halved I was able to use ice to calm it down enough I went back to sleep. Now normally a bad sprain can last weeks but no joke or lie feel nothing. This literally made it all about one hour of a struggle. Very happy with this can't wait to use on canker sores if it lessens how long they stay I will be one happy customer!
