User Reviews



KÜLKUF is a thermoelectric cooling device that immediately lowers body temperature during hot flashes. “Our award-winning, proprietary, patented Climacon® technology, developed at MIT by our founder, is the engine that powers Kulkuf”. The way it works is, to put it simply, sending a safe amount of electrical current from one metal connection to another, causing one to heat up and the other to cool down.

KÜLKUF comes with an adjustable temperature range operating at three levels: 45 F(7°C), 50 F(10°C), and 54 F(14°C).

Of course. KÜLKUF can assist you anytime. Just turn it on when you feel a night sweat coming and go back to sleep. It will automatically turn off after five minutes. Note that your wrist should be facing upwards so that the heat extractor can work efficiently.
Our regular-sized wristband fits 80% of women just fine. If you have a small wrist, you can try our medium-sized KÜLKUF. You can check out our Size Chart on the product page for more information.

The battery life depends very much on the temperature settings and frequency of use. For the average menopausal woman, KÜLKUF can relieve hot flashes for up to three days on a single charge. Turning on the wristband more than six times a day, and keeping it working for over 4 minutes each time, might require more frequent recharging.

KÜLKUF cooling bracelets for hot flashes utilise patented cooling technology to provide rapid relief from hot flashes in under 60 seconds. By harne­ssing the power of evaporative­ cooling, this innovative design effe­ctively draws heat away from the body.

Yes, the KÜLKUF cooling wristband is crafted for e­xtended wear, offe­ring continuous relief from hot flashes throughout your day. Our wristbands are­ lightweight, comfy, and discreet, pe­rfect for everyday use­, whether you’re at work, home­, or out and about.

Yes, KÜLKUF firmly upholds the calibre and performance of its offerings. All our bracelets for hot flashes and accessories are accompanied by a thorough 12-month warranty, couple­d with an unconditional 30-day refund policy. This dual assurance ensure­s your unwavering contentment with e­very KÜLKUF acquisition.

The KÜLKUF wrist bracele­t for hot flashes provides targete­d relief, specially de­signed to manage hot flashes, unlike­ traditional cooling methods like fans or ice packs. Our advance­d cooling technology offers rapid, long-lasting comfort without the ne­ed for messy gels or cumbe­rsome equipment, de­livering relief tailore­d for hot flash management.

Yes, the­ KÜLKUF cooling wristband takes the top spot as the best hot-flash cooling bracelet! It’s your trusty companion for kee­ping cool and comfy during workouts.

    I am so thankful someone came up with this!

    It may be an expensive purchase but so worth it. I am on day 8 and loving everything about it. It is a bit large but you get used to it. It cools very quickly and you can pick from three temperature settings which is great!! I would definitely say it works as stated, l have no cons against this great product!

    A product I didn't know I wanted but needed

    I am so glad I found Kulkuf! This device is exactly what I needed for my hot flashes. I did not think I would ever find a solution but here it is. In a matter of seconds, my hot flashes are gone! I’ve stopped worrying about them since I have my Kulkuf wristband. I do wish it was sleeker and had an edgier look to it but it’s an amazing product and I swear by it. Your site only talks about menopause – Please include that it helps women with PCOD/PCOS with hot flashes too!

    Great Product!

    Great product that relieves your hot flashes in minutes I was diagnosed with prostate cancer a couple of years back and was put on hormone therapy and with it came hot flashes. I was not prepared for it and didn’t know how to deal with them until I came across Kulkuf and decided to try it. I was amazed at how quickly I felt better and my hot flashes completely stopped. If you experience hot flashes, here is your solution.

    Actual relief from hot flashes!

    After suffering from hot flashes for a year and trying out different ways to get relief with no satisfying results I decided to give Kulkuf a try. This product is really unbelievable! It shortens the length of the hot flash. I used to have one every hour! Now I only have to push the button and I’m done. If you suffer from hot flashes, do yourself a favor and get the Kulkuf cooling wristband.

    This item is a must have!

    I’m a very careful spender, so I was sceptical about spending $199 on this wristband. I was going to try it, and if it didn’t help with my hot flashes, I planned on returning it. Turns out it works great! It is an amazing product and I highly recommend it! As soon as I feel a hot flash starting, I push the cold button and it sends a cooling sensation through my body. I’m no longer dripping sweat. I even use it at night and it has really improved my sleep cycle

    I really am so grateful to Kulkuf

    I found the Kulkuf cooling wristband when I was really hard-pressed for a solution for my hot flashes. I got it within a week of placing an order and it works! I absolutely love that in under 60 seconds, my hot flashes are gone! I do wish the wristband was less bulky and more fashionable looking but I’m so happy that I don’t have to worry about my hot flashes anymore, simply turn it on and my hot flashes are taken care of!

    It works!

    I’ve had hot flashes and night sweats for over 10 years and ever since I bought the Kulkuf cooling wristband I have not had hot flashes and night sweats. That’s all I ever needed, relief from these menopause symptoms and I’ve finally found it!!

    It’s my go to for hot flashes!

    I’ve used this device for 6 months now, now I don’t even pay attention to my hot flashes after I switch it on. I had severe issues with heat intolerance. I use this throughout the day for hot flashes. It’s also super easy to use and I don’t go anywhere without it.

    The best money I have ever spent

    I first heard about this product from my close friend, she bought one and she swears by it. So I decided to give it a shot and it works. I have been using the wristband for over a week, and let me tell you the best money I have ever spent. I sleep better at night, feel relief throughout the day, and I don’t feel like I am going to actively combust. I cannot express how thankful I am to have found a product that works!!

    I don't know how it works but it does and is worth the money in my opinion. LOVE IT!

    I am a breast cancer survivor and due to my cancer drugs have been having hot flashes for more than 4 years now. I live in Boulder, Colorado and would go outside in the cold to cool down in the middle of the night when I got hot flashes. I got the Kulkuf as a gift from my husband. I was skeptical about using it but I gave it a shot and I’m never looking back! As soon as you turn it on and it stops the hot flash immediately, I go right back to sleep and I am not soaking wet from the hot flash.
