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.
