How do I know KÜLKUF works?

Tested on over 100 women with hot flashes, and 9 out of 10 reported a substantial reduction of hot flash symptoms in 60 seconds. Additional, testing at the world renowned Korey Stringer Institute demonstrated a significant re-duction in body core 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 return to sleep or remove it and place it on the nightstand.

Why KÜLKUF instead of hormones?

Most females 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. Additional, the long term cost of menopausal medications could easily be off set by a one time purchase of KÜLKUF.    

Does KÜLKUF come in different sizes?

No, as the Velcro allows one size to fit all. Simply adjust to a snug fit for best results.

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.
