Double Wall Color Frosty Freezer Mugs, 14oz, Set of Four, Assorted Colors (Red, Blue, Green, Yellow)

I am very satisfied with this purchase. They arrived on time for Christmas, were well package--the mugs of all four colors were individually boxed packed in a sturdy shipping box. The follow-up e-mails are a big plus. I've had a similar mug for a couple of decades; I am confident that with proper care--be sure to follow the usage instructions--these mugs will give equally good service. Now my four grandsons and I can all enjoy our root beer floats and milkshakes in style.

Gave these to my son for a Christmas gift! He loved them! Kept them in the freezer and never really had to use ice!

These hold a 12 oz can of soda, and will turn a warm drink cold. They don't stay frozen as long as other freezer mugs I've used, but they work well enough.

I bought a 4 set of these 10 years ago and they stood the test of time. Hubby threw them in the dishwasher and were toast after that. Yes they do have condensation on the outside that drips down but anyone who took science 101 knows if the inner core of something really cold it will eventually evaporate when introduced to warmth. I love these glasses! Hand washing is a must but well worth it considering how cold they keep the liquid inside. The bonus in their coloring makes it really hard for people to know what you're drinking. ;-)

After three weeks of heavy use: The polypropylene material seems very tough and scratch-resistant and the colors are great. But a couple of design shortcomings mean no recommendation from me: The handles are strangely narrow and thin, so you don't get the solid grip you expect with a mug. And the rim is extremely thin, so that, as you tilt the mug, your beverage cascades down onto the rim and sloshes into your mouth. Maybe the folks at the factory enjoy this; I don't.

I had one of these that I got at a garage sale. I kept it in the freezer right side up and eventually the base cracked and the freezer liquid leaked out. Keep Calm mugs in the freezer upsey downsey like the instructions say.

I received these cups on August 2nd for a birthday gift for my boyfriend whose birthday was on Aug 29th. He loves ice cold milk. He followed the instructions n placed them in the freezer as specified. Two of them cracked before even getting to use them once. I just picked them up from him today Sept 11th n was told by Amazon that they r not eligible for return. Shame on Amazon and the seller. I could see if they were old n had many uses but he just tried using them for the first time. As u can see from the photo, its cracked n the liquid inside is gone. This happened with two of the four cups.

The glasses work well, but I received 2 yellow instead of one color each as in the picture. Kind of a bummer as I wanted to use these as color coded glasses for my family.
