Iwatani Japanese premium Hot water bottle-2.8L with Soft Fleece Cover, Large capacity, long-term heat preservation, keep the body warm, dry and comfortable

Used it every night for a couple of weeks and so far it has been a very good bedwarmer. The size is small, but large enough to warm the upper torso or feet, depending on where it's placed. However, it must be wrapped in a towel or some covering to prevent heat burn. A warning info sheet is included in English. Be careful when holding the handle area when it's filled to the top because it is very hot. Wish a cover was included with the unit. That is why I gave it a four rather than a five.

Like the handle and sturdiness of this hard plastic hot water bottle. It doesn’t flop around like a soft one does. Not to bash soft ones as they have their purposes too. For example, this hard plastic one is not as comfy on your lap or on top of your feet like a soft one would be. But I didn’t purchase this hard one for that. I use it as intended. Bed warmer and it’s perfect. I don’t have to worry it’s going to leak if I accidentally roll on it or it drops off the bed. It does get pretty hot when you initially fill it up so I would use the fleece bag that it comes with if skin contact is your intention. Most nights I just put it on top of my bedsheet without the cover, then cover it with blanket to let it heat up bed before I get in. It does stay warm (not hot) through the night but it seems my soft hot water bottle stays hotter longer. Maybe because it’s soft and this is hard rigid plastic the heat doesn’t retain as well? Anyway, great bed warmed and lap warmer just a bit heavy for the lap and not as malleable as soft one.

My feet were too cold in bed so I bought this. It’s truly amazing like other people said in reviews. The bottle keep the hot water till next night!!! I love love love this Japanese product!!! Thank you!!! Thank you 🙏
