Not very sturdy. Spend a dollar more and get a good GSI cup

Works well

I bought this cup for backpacking. I enjoy it a lot because it fits perfectly on my Nalgene bottle (even with stickers all over my Nalgene). The cup is very compact, light, and useful. I picked this over the GSI camp cup because this is the best fit cup for a Nalgene water bottle. Initially I would have rated it a 5/5 But the quality is lacking. I tend to boil lots of coffee and after a handful of uses, the handles have become loose. They don't hug the cup tightly anymore and sometimes get in the way in cup holders. One of my handles can even come off the cup.

Cup appears nice but upon looking at the bottom it appears as if it was dropped on a sharp object , there is a visible dent and a raised line on the inside . The cup holds water but im not sure i would ever heat the cup up on a burner or fire so it doesnt form a hole in the thinned out dent.

For my bug-out bag.

Nice stainless steel cup. Fits well over a standard Nalgene bottle. Seemed well-made, except after a couple years a handle broke off (the thin stamped plate piece broke off from the welds failing). It looks like this could be better attached, or have better quality control over the welding process.
