Hot water bottle
My wife loves this water bag, it's comforting and easy to use, no issues, and the quality is amazing

So cute... so very... kawaii?!
I've lost my hot water bottle. Well, it's not currently available would probably be more accurate. So I was looking at getting a replacement when I stumbled across this, and it just made me go *squeeee*, even though I'm not the squee type. Given that my other half was due to come and visit, when I showed it to her (and she immediately coveted it), we arranged for her to bring one of hers, for me to order this, and for there to be an exchange! Having received it now, it's even cuter in person than it looked onscreen. The graphics are cute without being childish, and the quality of the various parts seems decent. There is a bit of a plasticky smell from the wearable holster, as well as the water bottle itself, but they fade in a few days. What was a pleasant surprise is that there is also an extra little pink fleece pouch so you can use the hot water bottle without the holster, and not get burned when it's still a little too hot. Given that i lack a uterus, I cannot comment on the effectiveness of this for associated ailments, but for keeping small feet warm, or stuffing under a coat, it's " Totemo tanoshī ".

Read before buying.
Don't buy as a gift for a baby or child--(the cover); but for an adult, this is great. All in all a pretty good value--unless you want to use the bottle cover (which is pretty, but not practical). I really like the belt feature--wonderful for back or belly pain. Also great for wrapping around a sore thigh. You can use it for a knee--if you are sitting. (Wraps well, but the velcro placement is not perfect unless you have an enormous knee.) If you are really chubby, this might not work for your waist without an extender piece. The bottle is very nice. The belt is soft and seems very durable. The only drawback is the bottle cover--which you might even want to use. The neck opening is so small that you have to literally roll the empty bottle as tightly as possible and then work a while to inch it into the cover. No give or stretch to the opening of the cover. After you work the bottle open inside the cover, you have to be very careful filling the bottle with the hot water--otherwise, you will have a soaking wet cover. Dumbest design ever for a water bottle cover! This is a Chinese knock off of a German hot water bottle for babies. (I have had a few and my kids loved them.) Except that the Germans were smart enough to cut a wide opening at the top of the cover and then to use tight elastic stitching that stretches as wide as the bottle (to let you put the full bottle inside the cover) and then snaps back around the bottle opening. To me, the best feature is the belt that allows you to walk or sit, while enjoying heat to the back.

Gets pretty hot!
I absolutely love this thing. I got it to soothe my mestrual cramps but really for the ones that feel like someone’s racing on my lower back. It’s a nice size and the waist band helps keep it against my back!! It comes with a little cloth cover and it’s very easy to use. It gets VERY HOT and holds temp for quite some time. 10/10 would purchase again

Great product with good quality!
I've had hot water bottles ,but this belt is a game changer. You can lay on your side with it staying on, you can walk around with it on you. I also like the separate cover if you want to use it without the belt. Both me and my cat are fully enjoying it(see photos).
