3.5 stars. Too small to fit ice cubes.
This feels really soothing, especially around the eyes.  I had a migraine with eye strain, and using this fresh from the freezer helped relax my eye muscles. The cold feels really good.  Though I suppose I could freeze a spoon and use the back of that instead, the ball works well.<br /><br />I like the roller ball part, but I don’t think the long, narrow shape of the tube works well.  It’s too small to fit an ice cube, and I’m not going to crush ice to put in there.  (I grabbed some fresh snow from outside to see if adding ice helps. ). I also wouldn’t store oils in there, because it’s not sealed, so the oil would spill if it tips over.  And the long, narrow shape makes it more likely to be knocked over.  The tube should be more short and squat, and should be sized to fit a standard ice cube.  So I like the roller ball because it feels good around the eye area, but the tube isn’t very useful to me.  I have it stored in the freezer so it will be nice and cold when I need it.
