Cute but break easily
I really wish I could give it 5 stars!! My only complaint is they chip and break so easily! I purchased 4, one broke in the dishwasher and the other shattered when it slipped out my hand in the sink. Mind you it was not a super far drop in the sink. One bump and they chip. I know they are glass but compared to other mugs they just break a lot easier. They are super cute and I really love them! I repurchased the 2 broken ones and we tried the dishwasher again after moving to a new house, and one still broke. So we are down to our last one and sadly won’t be buying more.

I bought two of these years ago. They’re beautiful, and I still have one that I love using in the mornings for tea or coffee. Unfortunately, the other one broke within a year or two. After reading reviews, it seems like that’s a common issue with these.

Cute but doesnt hold up
I love the way this mug looks, but mine did not hold up well at all. It shattered from the lightest bump of a spoon in my sink. So as much as I love the price and looks, I wouldn’t buy again.

Break extremely easily -- safety concern
They break extremely easily, leaving glass floating in your drink. Safety concern.

Waste of money
Waste of money! It’s not well made . I had to throw them all . It didn’t last me 4 mths . The double layer feature is useful and water gets trapped in between layer .

aesthetic but incredibly fragile like more than you think; I tapped it in the sink with a plate while doing dishes and it broke :(

Like other reviews have said it is fragile. It was given as a gift and one of the four already had a chip on the handle. Very light weight and feel cheap. Came online to see how much they were and I wouldnt have paid 8 bucks a pc for these. 1 star for cute aesthetic only.

NOT dishwasher safe.
Absolutely NOT dishwasher safe. The plug for the space between the inner and outer glass surfaces fails reliably. They last perhaps 6 months. We went through alt least 10 of them. None was mechanically broken but seals always fail

Nice cups but break easily
The cups look nice but shatter very easily, both broke within a week of purchasing.

I love this cup. My first one broke because I dropped a kitchen scissors on it in the sink. :( So I immediately bought a new one. I also microwave my beverages in this cup. Works great!

Highly reccomend!
These mugs have been phenomenal with my nighttime tea and morning coffee. I purchased two and they work great with both super hot and cold beverages and are super cute. (I saw a lot of reviews complaining about this product but took each one with a grain of salt. Yes, these are lightweight GLASS mugs and should be treated as such. Glass shatters *when you drop it*!) As with other glass cups, I recommend handwashing them and not leaving them in the sink where they could get knocked over. I will be purchasing more because they are a great value for their price!

Seal Fails even if you handwash
The coffee/tea cup is great, until the seal fails and you start collecting water in the walls of the cup. My first one lasted 3 months. Purchased a second one and the seal failed even faster. I just got annoyed and trashed them both.
