Sure did keep my coffee hot for over a 5 hr period. Had coffee in the morning early 5 am. But full day of driving to doctor appointments for my Mom. I knew I would need a pick up (I love coffee) so best time to try my new Mug. So at 3 when I really took a break so great to say ahh at 3pm sitting outside still hot and great tasting due to the ceramic. Great great combo!
Look it’s pretty awesome and for the most part I never write reviews it’s just that it doesn’t fit in any standard cup holder for like your car or whatever. That’s frustrating and I suppose I should have sussed it out before I bought it but I couldn’t tell from the picture and I didn’t think that it wouldn’t fit. Neve crossed my mind. Would be perfect if it did.
