I have about a half-dozen of these. One of the attributes I like is that - compared to other glass coffee cups I have owned - they are relatively hard to break. I broke one upon dropping it from about waist high to the hard floor, but a number of times I've knocked them over on a counter and they have not broken (to date). I find that the Hario double-walled glasses are more prone to breaking. As other reviewers have noted, the coffee in these lose heat quickly. When I want to leisurely sip my coffee over an extended period, I go with the thermal version of these, which are great for that purpose.

I always felt bad that I preferred the way coffee tasted in a paper cup. Every reusable cup I've tried either gave the coffee a metallic taste or was so tall that the foam of a latte would float and stay at the bottom of the cup when taking a sip. This cup is made out of glass so no metallic taste and it's the same size as an 8oz paper cup which is perfect! The only downside is that the lid is hard to remove, but it's good that it protects against spills.

I bought this for my boyfriend and he loves it! He uses it every day to take with him in his car. He makes his coffee at home and then takes it with him. He said it holds the heat and he saves money by not having to go through a drive-through coffee outlet
