Doesn't work. Don't bother. Brookstone won't refund. Manufacturer won't take it back either. You will be ripped off your hard earned money.

This is one of the worst products I've ever purchased and even though there are literally thousands of unsatisfied buyers of this product Brookstone will not stand behind their product. It is extremely uncomfortable and left me with headaches that lasted for days and I only used it for about 2 hours. The Brookstone employees did not care to hear about the problems with their product only the fact that you can't bring it back. Never again will I buy from Brookstone if they do not care about quality,design or most importantly customer satisfaction.Eric EMonroe Mi
