The 3in1 hot water bottle belt from KUNU® is the perfect companion for cold days and for stomach, back or neck pain. Long-lasting warmth is guaranteed by a hot water bottle made from sustainable natural rubber. In addition, an extremely fluffy cuddly cover for the bottle made of soft, low-lint fabric ensures a cozy feeling. The matching belt can be flexibly adjusted to the right length thanks to the Velcro fastener and is made from the same material, which is suitable for the washing machine (30°) and tumble dryer, ensuring an all-round hygienic experience. In our practical test , the combination of hot water bottle and belt was convincing, but we were also impressed by the lovely package design and the certifications the product has undergone.

*The maximum score is 100 points
The 3in1 hot water bottle belt from KUNU® performed very well in the practical test. The flexibility that the product offers is particularly noteworthy. The belt and bottle can be used separately, but when combined, they develop their full potential as a practical warmth companion in any everyday situation.
The extremely soft and fluffy fabric of the cover and belt guarantees a pleasant feel. The cover is suitable for both the washing machine and tumble dryer. Tests have confirmed that the cover retains its shape even after a 30° wash and subsequent drying and is still incredibly soft and cuddly. The fabric is also low-linting and did not leave any marks on various items of clothing and furniture in our test after it had been washed once. At the same time, the bottle has a convincing look and, just like a cushion, fits perfectly into a cozy living environment that radiates peace and relaxation. In the endurance test, the warming effect lasts even after several hours. The product therefore provides a reliable source of warmth throughout the night, for example.
In our practical test, the belt provides a comfortable hold without slipping, both with and without a hot water bottle in the insert. Thanks to the flexibly adjustable Velcro fastener, the belt can be worn in any situation.
The only point of criticism is that the hot water bottle with a volume of 1.5 L and a capacity of approx. 1 L promises a pleasant design, but a slightly larger version would be desirable for the future.
Price/performance ratio
and ratings from consumers
ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Price / performance ratio | Very good performance in the upper price segment | 70 points |
| Rating cut | 4.8 out of 5.0 on Amazon | 90 points |
| Total | 80 points |
*The maximum score is 100 points
On the Amazon platform, consumers rate the product with an average of 4.8 stars. One common criticism is that the heat output is reliable but not at the desired intensity. Many customers like the extremely soft fabric and the high-quality workmanship of the product, as well as the flexible application options of the hot water bottle and belt. In our practical test, we were able to confirm that this is a high-quality product with a very pleasant feel on the skin and a high-quality finish . We can only share the criticism of the heat output to a limited extent, as it should go without saying that using the hot water bottle directly on the skin generates more intensive heat conduction due to the thick, soft fabrics.
Prices of up to €26.99 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €12.99. The 3 in 1 hot water bottle belt from KUNU® is therefore currently in the upper price segment with a price of €22.99. The price-performance ratio is reasonable for the quality and performance received.
