I wanted a titanium cup, but the price was a bit too much for me so I ordered this one. I'm not a HUGE fan of the handle design, but it works. It's solid, holds a 32 oz Nalgene bottle nested inside snugly, and appears to be very durable so far. I have not tried heating with it yet, but don't see any issues occurring when I do. Solid cup! Only four stars due to the handle design. Would have given it 5-stars if the handles were more vertical than horizontal in design.
