I ordered this to replace the exact same one that I have been using nightly for 6 years. These work 10x better than any standard heating pad so if you suffer from aches and pains or sore muscles, this thermophore is pure heaven. Definitely worht the money - just make sure to lay the cord loosely on the thermophore when its cooled and gently roll it up - do not roll thermophore up and then wrap cord around it (like many women do with curling irons) as that will shorten its life due to cord damage. :)
