The review is for Sawyer The Extractor™ Pump Kit aka snake bite kit.
Check out what this NC dude said: "Not sure if this is what the guy in Alabama used when he got bit by that rattler, but my wife insisted that I get it. She has always been scared I would get bit by a snake and insisted I carry her breast pump in my truck. This will at least make it where I don't have to carry that other device around and it is smaller. Looks like it will work, I hope I never have to use it. Also no batteries required."
