I bought this because I was tired of paper cups. It's perfectly sized for traditional cappuccino, looks great, the glass is thick and feels solid, the rubbery grip is soft, easy to hold and doesn't get too warm. The lid makes for comfortable drinking and is reasonably spill-proof (it's not a tight lid, though, so don't go for a run with your coffee). The lid did have an unpleasant, plasticky smell when I first unpacked it, but after I put it in the dishwasher, that was gone.
There is a 2-star review on here for another color of the same product, saying that this cup doesn't keep the beverage nice and hot for an extended period of time. That might just be because the Joco Cup isn't a thermos. :-) Seriously, it doesn't hold the heat any better than any coffee mug you have at home. It's single wall glass. But it's meant (and advertised) to replace the omnipresent to-go paper cups, and it's doing a marvelous job at that.
I'm using it every day and am very happy I bought it!
