I've used the same product for past 5 years now and ordered 1 again. This is just amazing and very easy to use. Quickly gets warmed up and ready to use in minutes which lasts for quite some time. I highly recommend this to anyone looking for such product.

This compress its just warm enough for soothing and giving pain relief unlike the traditional rubber based compresses containing water that get super hot. the compress gets auto shut off after heating 10-15 mins. the red cloth cover is super comfortable and cozy to the touch. if you need a hot compress, this is not for you. I was that person until I used this and realized the warmth (the right temp) provided worked as needed. the best part is, there is no requirement of adding hot water to this product. you simply need to plug in and it will heat up for use. it's helpful for mentrual cramps and back/neck pain relief. I am providing a pic here to show the product size in comparison to my hand.

I have had this hot water pad for around three months. I have had post Shingles pain for seven months and this pad helps me when the pain is severe. The pad heats up between 5-15 minutes depending on how often you use it. The heat lasts from 2-6 hours just as listed. The pad will be quite hot when it is done charging. I like to put it under a blanket while I am laying down. Make sure you do not use it while it is plugged in. Also when the pad is almost done charging it makes a buzzing noise as a reminder to unplug it. I would recommend this to other buyers. So far I am quite pleasedUPDATE: I purchased another heating pad as the previous ones were getting well used and would not heat up as much as they did when I first bought them. The new hot water pad is just as good as the previous pads. I have been suffering with post Shingles nerve pain for over2 1/2 years and they help take the edge off the pain. I again wrap the pad in a towel after heating it up. This helps keep it warm for a long time. Make sure not to use the pad while it is plugged in and do not put in on bare skin without wrapping it. The heat is quite hot at first but as time goes on it will get cooler. I hope this helps those who are in need of help with pain.

this hot water bottle is too good, it is safe, it stays hot for long time... works very well if i get any back pains… also, fabric bag is soft and comfy.

Heats fast and retains heat well.

I bought one in Asia and was desiring to find a second one. It definitely keeps warm up to 5 hours and has been useful. Worth every penny

I use this mostly to warm up my feet when I get into a cold bed at night.Pros:1) It heats up quickly.2) It gets quite warm. In fact, it gets so warm that I can't have my bare feet touching it for long (when it's just been heated).3) It stays warm all night, granted it is under the covers all night. When I remove it in the morning to make the bed, it is still a little warm.Cons:My only complaint is the "sandwich" style charger, which makes it a bit more cumbersome to plug in. My first model had a regular charger and it was very easy to use so it's a bummer they changed the design.Overall, I'm really impressed and this has helped me fall asleep faster when I get in bed and my feet are cold.

It has no quality and does not heat at all

I've had two of these. I purchased one at the end of February this year and have basically used it for a month. It just died on me. The same thing happened with the first one. I like the product so I gave it 3 stars. The concept is a great idea. However, because I have had bad luck with durability, I can't recommend buying this.

I initially liked my Happy Heat Hot Water Bottle! It was a game-changer as a cozy companion for chilly nights. Initially, it warmed up quickly, providing soothing relief to my stomach and neck. However, over time, I noticed it took longer to heat up. Sadly, after 5 months, it stopped working altogether. Despite my best troubleshooting efforts, it just wouldn't start heating again. While it was great at first, its longevity was disappointing.

Bought this product for my mom on June 26, 2023 and today is October 13, 2023. That’s it! I read some comments today and others had the same issue! Wouldn’t recommend it at all! Felt like scammed $90 plus Canadian Dollars!

The product stopped working after 5 months. 30 day warranty. Will replace with a different product with a better warranty.

I use it for my back it works

I’ve had to buy a new one about once a year. I use it almost year round. It helps me sleep when my sciatica is acting up, which it usually does whenI lie down. I find it a million times better than a heating pad because it gives radiant heat. Highly recommend

I use this for everything from period pain, to muscle pain, to comfort after a bad day! As a college athlete I find it vitally important for both physical and mental health! Would reccomend

Last year I bought this items and doesn’t work properly after few months. Then I also bought another couple month ago and it only works good few times and then fail to work. After few time it is not enough hot for pain relief. As once we purchased, there is no way to return this item. This is a one of the worst item that I have purchased in my life.

Absolutely love this! It was referred by a youtube channel and it is amazing. Hint from the youtube channel: it will stay hot longer after the first couple/three uses...stayed hot for them up to eight hours in very cold weather! I highly recommend this product for sore muscles and joints! Enjoy!

Didn’t work with my region electricityBroke second time I used it :(

I love my hot water bottle so much that I gave this one away as a gift. She said she doesn’t get to use it as much as she wants because a family member finds it first

I just love this hot water bottle. It stays hot for HOURS. It is a bit hot right off the charger so be sure to use the cover included -or- you could make your own thick felt one. My daughter stole my old one so I had to get a new one.
