    Put one into refrigerator for cold drinks and the handle came of at the rivets not sure if that's due to the cold temperature or not

  • Great mugs that don't tip.
    Verified Purchase

    Love these mugs. They have saved from many a spill as they are not prone to being knocked over like a taller insulated coffee mug. WIsh they were still available as I bought them years ago. First found them at *** and paid a mint. They no longer carried them, but found them here at Overstock at a fair price. Too bad they seem to be permanently gone.

  • Keeps Liquid Hot
    Verified Purchase

    This was an excellent purchase! The mugs are sturdy, the tops fit perfectly, and they do their job extremely well. The rubberized bottoms keep them from sliding around. My husband uses them for tea, and he's found that the liquid stays hot for hours. If he leaves it in the mug until late afternoon, he finds it's still lukewarm/room temperature. Easy to clean. Indentations on the sides make them easier to grasp if not grasping by the handle. Have had for about a year now and the handles have stayed on. Tea does stain over time, but stains can be removed by making a baking soda paste and letting it coat the mug for a while--scrubs stain right off. These mugs are used almost daily in our household.

    I purchased these and was disappointed that the handles on both broke off after less than a month's use. the handles are a little awkward to use as well, and the cup tends to get pretty hot, so beware your lips when sipping.

    Big problem is that top of mug so easily comes loose when you're holding or drinking. Result is that beverage spills out on hand or clothes. It simply needs a firmer commitment to the mug. Without this design improvement, it's a non-starter. With it, I'd be quite satisfied. I bought two mugs at once and both have this problem.

  • Perfect size
    Verified Purchase

    We needed cups to fit under the coffee maker dispenser and these were perfect. The lid doesn't stay on well unless you make sure and give it an extra twist to be sure it is snug. Not so sure I woul want to travel with it!

  • Awful for the price and not meant for beverages on
    Verified Purchase

    On the site these look nice, lids pop off with coffee in them due to expansion of the metal. Very cheap metal , for $XX I expected nice!

    I exchanged the original order because the lids were not secure and tight. They tended to pop off. The replacements are a bit more secure but not much of an improvement.
