Bodum 15oz Double Wall Latte Mug, High-Heat Borosilicate Glass, Set of 2, Clear

Why did you pick this product vs others?:I find they keep hot drinks hot longer than others Unfortunately I broke one after one week and sinceIt's double walled it was a lot of glass everywhere

Why did you pick this product vs others?:Great brand , less fragile then other brands we used

Arrived on time and they work great.

Perfect size, and fits under the expresso maker fine, not too tall. Glass is perfect as well. Not sure why it says they are returned often

Perfect size! I wish I had seen these a long time ago. I have the regular coffee mugs by this company for many years and was delighted to find these. They are well made and worth the price. The handle is comfortable in my hand and the cup itself is very lightweight. It does keep my cappuccino much warmer than the other ones I have (which are now being donated). I wouldn't use any other brand.

I did this test for my own self because I really wanted to like these mugs to keep my tea hot longer but the results were disappointing. I will be returning the item. Am sharing this for other people's benefit --The two items compared:1) A porcelain (non-insulated) mug bought from the Dollar StorePRICE - $1Weight of empty mug - 325g2) This glass (double wall insulated) mugPRICE - $15 - $10 depending on which pack you buyWeight of empty mug - 251gI put exactly 300ml (~ 10oz.) of water in the mug being tested and boiled it in the microwave. Then, the stopwatch was started when the temperature dropped to 90°C and stopped when it reached 75°C. Each mug was tested separately. RESULTS--1) 6 min. 31 sec.2) 6 min. 37 sec.SO IF YOU ARE CONSIDERING THIS MUG TO KEEP YOUR BEVERAGE HOT LONGER, SKIP IT!!! The rest of the review is only more details.========================================Considering about 4 seconds margin of error due to how quickly I was able to start and stop the stopwatch while lightly stirring the water and taking a picture at the same time, both mugs performed nearly *identically*.REASONS WHY THE SINGLE-WALL PERFORMED SO WELL DESPITE GLASS BEING A SLIGHTLY BETTER INSULATOR THAN PORCELAIN:A) Porcelain has a higher Specific Heat (higher thermal capacity meaning the mug retained more heat when the water was boiled) thus helped in keeping the water hot longer.B) The porcelain mug was heavier (325g) so retained more heat compared to the glass one (251g)C) The porcelain mug had a white-colored interior, which is a good reflector of radiant heat, so it reflected the outgoing heat back into the beverage. The glass has virtually no color and radiates freely to the surroundings.Since nobody makes a vacuum insulated glass mug that is microwave-compatible so the only option to keep your beverage hot longer is to use a stainless steel vacuum insulated mug.

It's the perfect size for coffee, matcha lattes, or any drink! However, it breaks very easily—I accidentally pushed it into the sink drain hole, and it shattered instantly.Pros:- Looks great- Keeps drinks hot or cold- Double insulated, yet easy to drink fromCons:- Scratches very easily- Can break easily depending on where it’s accidentally hit- Moisture can build up inside due to the bottom silicone cap- Compare to metal insulated cups, it does not keep the temperature wellIf you're looking for a nice coffee cup, this is the one! Just be careful when handling it—it’s quite fragile. Other than that, I use it every day and absolutely love it.

The best cup for coffee I have ever used but one cup had a crack in the handle and it broke off. I do love the other one.Good that they come in two's.
