"Keeps it cold"
I use them for cold drinks and they work great. The ice is still in the glass long after it disappears in other glasses. They are really odd and quite striking as well. It is hard to get used to the feel of them though as they are very rounded and weigh almost nothing - strange sensation to pick them up.

"Practical Yet Pretty"
These glasses are great! I have a set of my own and love the idea of being able to drink hot and cold out of the same glass. And no sweating or rings on the counter. Plus they are dishwasher safe. I gave these glasses as Christmas gifts.

"Lives up its promise, but.."
I purchased the 6oz. 'Canteen' model, to try out with straight liquor on ice. I am more a sipper than a gulper, and with normal glasses, the ice always melts before I finish, diluting my drink. Overall, I have been very pleased with these Bodum insulated glasses. My ice lasts much longer, my drink stays cold, etc.

That said, there are always tradeoffs. The glasses have a lightweight, almost plastic feel to them. They lack the substantial feel of thick-bottomed Old-Fashioned glasses. I suspect that perception is exaggerated by the appearance of the Bodum glasses. At casual glance, the airspace between the two layers tends to looklike it is thick bottomed also - which it is not. When you pick one up, your are always mildly surprised at how little they weigh.

Another aesthetic tradeoff of the double-wall construction is the thick, rounded rim. It is quite unlike the hard, crystalline thin walls of a good-quality drink glass. My wife found this particular feature troubling enough to not use the Bodum glasses.

However, I do continue to use them. Despite all the compromises, they actually do fulfill their mission. They do keep your drink fresher, longer. I can hold the drink in my hand comfortably, and am not always looking for a coaster to put it down. I plan to buy a set of the larger size for my summer beer drinking.

"Bodum Double Wall Glasses"
These glasses are the best glasses I have ever owned. I will never use another type of glass. They can be used for both hot and cold beverages, you can not feel either cold or hot on the outside of the glass, and they don't sweat so you don't need to use coasters.
