I just picked up one. Seems pretty light and basic. Was under 40 bucks. Any experience with GSI products durability. My Pocket rocket, fuel can, and matches fit inside along with my cooking spices. I considered the Snow Peak mini solo cookset in titanium hope I didn't make a mistake. lol
It really depends on your style of cooking. With the GSI pot you can do some actual cooking, but if all you are doing is boiling water then I would have gone for the mini-solo, Trek 700 or SP 600 pot/mug.
As for the durability, my wife and I use the duelist when car-camping or if we need the bigger pot and it works just fine. It is a neat little system that will last a lifetime with proper care.
