I'm wanting to buy a heating pad that I can lay on a person's back after I'm finished in that area. I've seen the ones that you microwave and also ones that plug in and would like some feedback/reviews as to what you all use? I would think the ones with beans or corn hulls of some kind would slosh since I have an eye pillow that does that. I've seen heating pads that you plug in with some kind of sponge that you wet and it keeps it moist heat. Ah, and the Thermophore heating bad...moist heat with no sponge??? I would like it to be flexible and comfortable on their back. I have an older heating pad that I don't use, and it's pretty stiff. I'd also like it to heat up fast and do any of you find the cord to be combersome? I have an outlet right next to the table but.... Ok, let me know. Thanks!!!
