Title: Smart temp hot/cold pad
Review: We had previously purchased this product at Medic Drug store in 2004 and it served us well until late 2012. The instructions gave a heating time of 4 minutes for the larger pad. We would microwave it for 4 minutes and the pad held the heat for a couple of hours. Ultimately, the pad had some leakage, so we discarded and ordered the product through amazon. The new model instructions give a heating time of 2 minutes, which we followed. The pad is obviously not as warm as the previous model and does not hold heat as long. After a couple of weeks of usage, the new model began to leak, so we had to discard it. We haven't called the manufacturer about it. Very unhappy with the "new and improved" version.
