I think the idea ansich well. BUT: one may mask the only heat in a double boiler. that annoys me in the long run. Because one must also pay attention to the temperature, etc. Then always "matched Chechnya". Relatively awkward somehow. the next "problem", the attachment to the elastic band. Sometimes they slip through the eye and you have Only release "by fumble". If, for example. Cotton pads has also been heated and then have to start all over again to fondle you are cold. However, for this price tolls just as yet to accept. Is've yet another similar product ordered that these problems do not have, or for micro suitable. Although then cost twice but the water annoys me already huge when you should do it regularly.
