Absolutely love the Peppermint Halo! The cooling, tingly sensation is amazing, and works so quickly to help relieve the pressure from headaches. I even use it when I need to de-stress a bit. I bought the wand a couple months ago and recently just opened the cap and the tip just fell off, and is now some where under my car seat, never to be seen again. Unfortunate since there's still a good amount left in it. Needless to say, I'm going to opt for the roll on next time.
