Great
I worked 5 hours in my yard.  When I came into my house, the back of my legs cramped above my knees.  It was difficult to stand up.  My wife had an unused tube of DEEP.  I tried it and immediately felt soothing heat to my legs.  The cramps went away in a few minutes.  I strongly recommend this product.  We purchased another tube.  Now we have one tube for me and one for my wife.
