The roll-on is superior in several ways. It avoids the greasy hands problem, and it is more effective more quickly than the salve in the jar.
Additionally, it dries out and doesn't smear like the salve.
My 92 yr old Mother loves this. Its easy for her to apply to her lower back and hips when needed.
What else can I say. I have bone on bone arthritis and this is one product that allows me to get through the pain.
