HEYPORK Microwave Heating Silicone Hot Water Bottle Bag with Knit Cover, Hot & Cold Therapies Back pain - Gift for Girlfriend,Mather,Valentine's Day

I typically get the larger "heat bottles" But I fill them with water and freeze them to use as icepacks.I get chronic migraines almost daily. (bad memory) & forget to put my large ones up, so I wanted to get some mini ones to go with my large ones.These are perfect! small but not to small, and the perfect backup that wont take up nearly as much space!So far it seems great. still gets plenty cold but not unbearably cold. (it does come with a cover as well)seems like it will stay frozen for a few hours too. :)I like getting these over plastic icepacks because I have kitties that tend to rip the normal ones. I like the bottles because they are a lot thicker (silicone in this case) and the cats have never been able to rip my big ones, so hoping this will be the same! so far its good!

** Please note that I will revise this review as needed once I've finished my test run of the product. **I have purchased a current total of six of these longer bottles due to a recent surgery to use as ice packs. I inspected each bottle closely to make certain there were no issues, and filled each three-quarters of the way full, and squeezed all the air out right up to the top of the opening before screwing the lid down. I have laid each one flat down in my freezer. I have no intention of putting them in the microwave, but instead will use a kettle to fill the bottle with lightly simmering water instead, as putting sealed items into the microwave is dangerous, and anyone with the tiniest sliver of common sense would not do it. Don't be lazy, use your other kitchen tools: your kettle, and cooking thermometer. Perhaps it takes longer, and perhaps it is "Old Fashioned", but at least it won't explode in your face or damage an expensive appliance.Feel better, dear readers-- and be safe!Best Regards,M. ParxUpdate Time! It works fabulously as an ice pack, even when mostly thawed it's still ice cold. No leaks, either. I have zero intention of putting this in the microwave, but will eventually use it as a hot water bottle in the winter. I'll be putting carefully simmered water into the bottle. It's just safer. Anything else would be dangerous. The microwaves they want you to use are extremely low level, which barely exists in the modern world. Just put the kettle on instead and don't let it fully boil.

This is the cutest little bottle bag. Quality is superb and works great. Got it for my daughter and it does the job!

This water bottle is amazing! It’s all silicone and a little plastic ( lid and stopper). Super cute pattern on the bottle itself, and it’s sweater is pretty friggin’ cute too. It’s also functional; it keeps you from being scalded by the silicone when it’s hot (or cold!). The fact that you can microwave this or freeze it is literally the best thing ever. I use this for period cramps mostly, but I’ve also used it for my shoulders and back. When it starts to lose heat I just pop it back into the microwave. It’s great. I’m probably ordering more so I can cover my whole body in them.

Cute hot water bottle, perfect size to out it on your lap of you're sitting. Keep the warm for a long time and easy to use. Good for microwave too, even if I use mostly a kettle for it. Soft sleeve too!
