Swapped this onto my WhisperLite and it threaded right on with no fuss, priming like it should. The lighter weight is a nice bonus on longer trips, though the pump cup needed a little oil to loosen up at first.

Pumped up my old liquid fuel stove with this and it primed way faster than the original I'd been nursing along for years. Nice and light, and the pump action feels solid without any sticking.

Swapped this onto my WhisperLite and it threaded on first try with no leaks at the fuel line. The pump action feels smoother than the old one and it's noticeably lighter in the pack.
