Frequently asked questions

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(12°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.
You will find a USB cable in a KÜLKUF package compatible with any cellphone (5V) charger/adaptor that plugs into any standard power sockets.
Most women who participated in our clinical trials reported instant relief from menopausal hot flashes. Kulkuf cools down to 45°F in seconds and has three user-controlled temperature levels.
The KŰLKUF bracelets have a battery life of one and a half hours per charge. For an average woman, this should last for three days. If your hot flashes are more frequent than six times a day and last longer than four minutes, you may need to charge more regularly.
Of course. KŰLKUF has been tested and tried on men with immense success. No matter the cause of a hot flash, menopause, andropause or chemotherapy, KŰLKUF provides relief for everybody.
Results from our trial runs indicate nine out of ten people experiencing chemo-induced hot flashes have benefited from KŰLKUF wristbands.
KŰLKUF is designed to cool down hot flashes immediately and faster than any alternative treatment. Reports from clinical trials have proven the technology to be highly effective/successful.
Yes, absolutely. KŰLKUF relies on the natural thermoregulation mechanism to lower the body’s temperature. As an external cooling device, it hasn’t displayed any side effects during trials, and moreover, we haven’t received any reports from our customers about undesired aftereffects.
KŰLKUF uses DHL delivery to ship packages free of charge.
Within the US mainland, you can expect your package to arrive three to five days after shipping. Shipping usually takes up to 48 hours (business days).
No worries. KŰLKUF has a money-back guarantee, valid for 30 days. We’ll take your wristband back, no questions asked, and refund you ASAP.
All of our KŰLKUF wristbands have a 30 day after purchase warranty. In case of a manufacturing defect, we will replace your product for up to 365 days free of charge.
KŰLKUF wristbands rely on absorbing heat from your body and driving it out. For that to happen, you need to align the ceramic plate with the bottom of your wrist, which is responsible for cooling. In addition, the top heat extractor part of the wristband should always be unblocked for the heat to escape.
