VOBAGA Clear Coffee Mug Warm Beverage Mugs, Insulated Glass Cup with handle for Coffee, Tea, Water, Milk, Hot Chocolate, Juice, Best Coffee Gift for Family and Friend(Blue)

I really liked this coffee mug! I was looking for a mug that would work well with my mug warmer. Too many of the ceramic mugs I've used do not keep the coffee warm enough unless it's set on the highest setting. I assume this has to do with the physical properties of the ceramic, as well as the fact that ceramic mugs are not completely flat on the bottom so that they do not have direct contact with the entire surface of the mug warmer.This glass mug has no such issues--as a matter of fact, between the flat bottom and the conductivity of the glass, I actually had to turn down the heat level on my mug warmer so that the coffee wouldn't be too hot.The mug is very attractive: the borosilicate glass is of a high quality and very clear. And the handle (mine is a deep cobalt blue) enhances its appearance. All in all, an outstanding product that I will use often.

Perfect glass of tea, fruit, coffee.. Light, stable, looks good with color handle.

Left mine on the warmer and it unintentially got turned on high overnight. The coffee with cream boiled out and scorched the inside bottom, so I ordered a new mug just like it.. Maybe I will try to clean up the scorched one someday.

Nice cup, love the black handle!

This flat bottomed glass mug is a perfect choice to use with my Vorbaga mug warmer. I've used the warmer for a while now (It's really great, and I've even given a couple as gifts), but with this mug I can actually lower the temperature setting and still have a hot cup of coffee. It is lightweight, has a very comfortable handle, and holds a generous 12 ounces, so it's also perfect for water, or even the adult beverage I'm enjoying right now.

This cup is a plain, attractive design. It features a flat bottom that allows a cup warmer to warm it efficiently, without needing prewarming in a microwave oven. Works great for me all day long, especially in the winter. It is a bit thin, so I handle it carefully so it won't break. I have no idea how easily it would break, but it meets my needs perfectly.

I love how much these hold (2 cups!), and they are so light weight, which is great for my older, weak hands. The handles are big enough for my hubby's first 3 fingers (they're pretty thick) without squishing them together. Plenty of room for all 4 of my fingers. They are super easy to clean and don't stain. I would really like to have a full set of these!
