I've owned the earlier model, XK, for over 30 years. I've rebuilt it twice.
It has always been a solid performer. As noted above, it is heavy and noisy.
I'll use it now for group cooking (weight). I've gone to an MSR Whisperlite for winter use, and an MSR Pocket Rocket for three seasons use. I've found you can trust MSR products.
