I tested the 4 vacuum flasks I have and the Thermos performed the best after 6 hours.
Yes it works. In 5 hours is dropped just 12 degrees far better than the 26-26 degrees of the others I have of the same size.
Thanks snowys use are addictive!! Fast delivery received my flask yesterday used it for work as um on nightshift n kept me warm all 8hours. Get 1 today folks.
Awesome little thermos, surpasses the recommended 12 hr heat retention if pre-warmed with boiling water. Take to work everyday and can't fault product. Top quality at a great price.
