MEETRUE Microwaveable Silicone Hot Water Bottle with Cover( 1 Liter), Innovative BPA-Free Silicone Hot Water Bag Hot Water Bottles for Pain Relief, Hot & Cold Therapies-Gift for Women Children Elderly

I have had some hot water bottle so far, by far this is stand at the top of them and its material is outstanding.

I use these in bed at night. Pre-warm the bed. One at the feet and one in the center. Lifesaver for me in the winter. Under the covers these stay warm all night.

Repeatedly microwave just fine. Holds heat evenly as expected. The material doesn’t feel as warm as rubber. This bottle is much smaller than expected.

Better than rubber silicon can hold more heat and for longer.

Product is high quality and works perfectly. Best I have seen or used
