Double Walled Glass Coffee Mugs, 2-Pack 15 Oz Borosilicate Glass Coffee Cups, Thermo Insulated Glass for Latte Cappuccino Americano Tea milk Beverage, Clear

Great, Excellent

Excellent

I enjoy these glasses. It is fun to hold very hot or cold drinks without feeling the temperature. I blend powders and liquid in my morning coffee. The depth of the glass makes it easy to use a frother to mix my magic concoction.The down side is the lip feels a bit thick. And because of a plugged hole in the bottom of the the outside layer of the cup it must be hand washed. It looks very sparkly clean but when it dries the is generally residue left on the glass. It just takes a bit of extra cleaning.

These cups are perfect for people who have low tolerance to heat.. they’re perfect and amazing quality, don’t break as easily! They are comfortable to hold and are a great buy!

Update: I bought the name-brand one that these are knocked off of… it’s worth the money because they use a microwave and dishwasher safe silicon plug in the hole. Zero issues with those, so if you want nice double-walled glasses, get the more expensive ones, because you get a much higher quality product.Edit: Failed after 2 washes. Do not buy these!!! There is a tiny hole that is plugged, but the plug breaks or fails with minimal handling. I washed in my dishwasher on the top shelf… the holes opened up and water is now inside after 2 washes. When turned upright, they leak dirty dishwater out of the bottom.As others have mentioned, there is a tiny imperfection in the bottom that is sealed (barely) with a very thin layer of glass. If this pops, it will make a hole, which of course leaves you with a cup that is pretty much going to be a mess to wash and dry, because it will retain dirty water inside that leaks when upright (I had a plastic mug with double walls that had the same problem). My guess is this hole is where they blow air into the glass to make it hollow. Great idea, bad design/execution. You just have to be careful with these when washing.

They are great glasses, they do not get wet on the outside in the summer time..

These glasses are light weight and durable. They keep things cold as expected.

We bought these glasses in December of 2023 and absolutely love them.BUT - this morning (6/28/24) I took one of the glasses out of the dishwasher and the seal seems to be broken. There is water in between the glasses and it is leaking out.We only use them on Sundays for milk coffee and not on a daily basis. It says they are dishwasher safe.Not sure if we would qualify for a replacement?
