Bought the Express Lander a month ago and I've since taken it on a 7-day trip in Yellowstone plus used it a few times car camping.
It's performed very well so far. Things I like about the stove: (1) It's easy to light and lights reliably, (2) it burns with a hot flame and uses fuel efficiently, (3) it's light, (4) it's easy to start with cold fingers -- pump/fuel line, folding legs, valve, etc are all easy to use, even with gloves.
I had one problem with the stove early on, but it looks like that was user error. The proper way to shut down the stove is to flip over the bottle to let the fuel in the line burn up and the pressure equalize. Then you can unscrew the pump from the bottle. I made the mistake of turning off the valve and taking off the pump a few times, and the pump wasn't holding pressure well. Fortunately, I had bought the pump repair kit and a little fresh silicone grease on the pump head fixed the problem, which hasn't recurred since. That's all to say, when you're giddy to fire up your first pot of tea with a new stove, read the instructions for shut down, not just start up.
20-some uses in, I'd recommend the stove.
