These are a game changer for me!! They were able to keep my coffee nice and warm, with the lid on, for 45 mins!! Yes I am prone to distractions and often 'find' my coffee after some time since making. The outside never heats up so easy to hold when the liquid inside is piping hot. By the same token they kept hubby's beer really cold and again the outside was not cold. These are really durable and fitted well into the cup holder in our chairs. Great item!!
