Beurer Cosy Heated Foot Warmer FW20 5 "Cosy toes!" Jo 14 March 2018 Gave this as a gift to an elderly relative and was mortified when she handed it back saying it didn't get warm enough - she compared it to her radiator! As I have suffered Raynauds Disease for many years I tried it myself and thought it was excellent. Can only think that how cold your feet actually are when you put them in is relevant. I tried to explain without success that warming up too quickly can give you painful chilblains that take weeks to get better - as I know from experience. A note from the team Thank you for placing your review and for your feedback. We're pleased to hear you've enjoyed using it and hope your relative has found a suitable alternative.
