Review (4/5): I keep it the freezer :)
My friend got one of these and I liked hers, so I got same one. Seems to be of good quality. There are ones out there that are lots cheaper. Not sure if they are same quality as this one. I went with this one because I knew what I was getting. I keep it in the freezer and roll it on my face to refresh myself. Helps with headaches too.
