I've used my X-GK for many years and it works great. OK, not much for simmering so I won't be making any balsamic reductions on the road, but....
I use a Jetboil to make coffee, or anytime I just need to heat water; that's most of the time really. Got the French Press kit and truthfully, I seem to use it more than anything, because it's quick and easy.
