Fabulous... feels just like the professional's
I love this roller. I had my first experience with a cool roller after a face treatment. The nurse's roller is professional and made of titanium.  Hers retails for $350.  She recommended the stainless steel for a much lower price, and I can't tell the difference.  She stated a stainless steel won't stay cold as long, which she needs in her office.  Mine was plenty cold for a plentiful time period.  Out of the box, mine had a small squeak, which I read about in some reviews.  I easily popped the roller off, rubbed a tiny bit of coconut oil in the connection, popped the roller back on, and no more squeak.  If I get a tiny bit of coconut oil on my face, which I doubt will happen, that's probably good for my face too.  I cannot sing praises high enough for this product.
