Good cup !! Only wish it had a foldable handle.

Great for having hot drink and easily washed. Would not take it backpacking or hiking since weighs much more than a much more expensive titanium versions, but OK for taking to ski area in a lunch bag left in lodge - great for making tea in lodge-supplied boiling water. The volume markings stamped into side could hold bacteria if not properly washed, and are essentially useless, but not enough to make it a great, cheap cup. Had to use needle nose pliers to crimp exposed tiny sharp corners where body of cup is crimped around wire which extends out for handle, but easily done and not a reason not to buy it. These things caused me to give it only 4 stars.
