like i have said repeated times here on Hot Copper i have used the originals and have more than had the extra 38% intake and it can be used over and over if so wished it is quite durable and it does come down to yourself for replacement you must remember that there are hundreds of millions of people in the world that can buy this product and also many people will lose them or misplace them so there is many sales to be had the product does work its not a gimmick whether the consumers will wear them like myself, is the million dollar question if theyre like me THEY WILL and the product will be a SUCCESS
