Rated 5 out of 5 by Val55 from Keeps my coffee hot! I've had one of these for about 2 or 3 years and absolutely loved it. I also bought a tall one to see which I liked better. Unfortunately I had a disaster today when one fell on my tile floor. Luckily they are on sale today so I am buying 4 and giving 2 to my daughter so that my coffee will stay hot at her house, too!Date published: 2019-04-03Rated 3 out of 5 by JenJen from Great... but they break easily! We really enjoy drinking coffee from these mugs, although, they break very easily for such an expensive item.Date published: 2018-12-17Rated 1 out of 5 by LauraG425 from Water stuck between walls I purchased these in store with a gift card that we received for our wedding. Initially I loved them and the box claims that they are dishwasher safe but after only one or two uses there is now A LOT of water stuck between the double wall of the mug. And it will not come out. VERY disappointed.Date published: 2018-09-25Rated 1 out of 5 by Leaky Cups from All cups leak. Bought 4 cups and all 4 cups leak. Each have a small amount of water inside the supposed sealed liner.Date published: 2018-07-07Rated 5 out of 5 by AEades from Beautiful! I love these mugs! The coffee looks beautiful inside these and it's fun to use them with guests. I prefer to hand wash them, although they have been in the dish washer a few times.Date published: 2018-04-17Rated 1 out of 5 by Kaitlin B from Water trapped in between double wall glass. There is a small circle of adhesive glue which seals off the air layer between the double wall. This adhesive glue came off quickly after first wash exposing a small hole in the glass allowing water to become trapped within the space. The hole is too small to effectively get the water out.Date published: 2018-02-18
Have you fixed the problem with the leaking between the two glass walls?Hi RoniN, The factory has rerun testing and isn’t currently experiencing any issues with leakage.Date published: 2019-03-04
Are these microwave safe?Hi NYC1, These mugs aren't microwave-safe. The air sealed between the two walls can expand from the heat and cause the glass to burst.Date published: 2019-02-02
