Love This Product!
I love this product---it's well made and sturdy and is so versatile in it's possible usage! I use it in the morning to feel refreshed, and it seems to tighten my skin a little, too. I am prone to walking into furniture and getting large black and blue marks, and rolling the Hansderma roller over the area immediately reduces the discoloration and any possible swelling. I would think it would be good to use on children for their various 'boo-boos' as it is soothing and would take away the feeling of pain. I live in a very hot climate, and am looking forward to using it during the summer on my arms and shoulders (and stomach!) to cool off. Unlike another reviewer, I think the roller stays cold for a long time.  I take it out of my downstairs refrigerator and bring it upstairs to my bedroom to use, and often don't return it for a couple of hours, and it is still very cool when I do return it.  I also think if a woman is experiencing hot flashes or night sweats it could be used effectiviely for relief. And it's safer to use than ice to reduce swelling after any kind of surgical procedure because there is little chance of skin burn.
