Happy KÜLKUF customers

"Kulkuf is enough! I was skeptical at first, but WOW, it stopped my night sweats and allowed for a good night sleep, just like you said it would. I wear mine all night and just push the button when I have a hot flash and go back to sleep. The five minute automatic cut-off is a great feature. I also use it in the mornings while getting ready for work. I love it! I carry it with me everywhere. I never know when a hot flash might occur. Thank you KULKUF!" - Laynie

How do I know KÜLKUF works?

KÜLKUF was tested on over 125 women with hot flashes and while 100% of participants reported a substantial reduction of hot flash symptoms, 9 out of 10 described resolution of symptoms in less than 60 seconds. Additional testing at the world renowned Korey Stringer Institute demonstrated a significant reduction in core body temperature using our ClimaCon® cooling technology.

Does KÜLKUF help night sweats?

Absolutely! Just place KÜLKUF on at the first sign of a night sweat. KÜLKUF automatically turns off in 5 minutes, so you can leave it on and go back to sleep or remove it and place it on the nightstand.

Why KÜLKUF instead of hormones?

Most women are not willing to take the increased risk of stroke, heart attack and cancer, all of which are associated with the use of hormone replacement therapy (HRT). Until KÜLKUF there were no effective alternatives for the treatment for hot flash symptoms. Additionally, the long term cost of menopausal medications could easily be offset by a one time purchase of KÜLKUF.

Does KÜLKUF come in different sizes?

Although our adjustable regular size fits most female wrist sizes, occasionally a slightly larger size is needed. If in doubt, simply measure the distance around the wrist and if the distance is greater than 7 inches, request our larger size for maximum comfort.

Is it normal for KÜLKUF to become warm when it shuts off?

Yes, occasionally the KÜLKUF will become warm immediately following use. This is simply the discharge of accumulated heat from the heat sink, and is perfectly normal.

One year warranty against defects in materials and workmanship. 60 day battery warranty.
