That's one opinion, Snake_doctor. With respect: There are a great many opinions (and numerous threads on this site)and there are studies which don't agree with you. In the OP's link I'm not persuaded by "the doctors said" that if the patient hadn't extracted venom he wouldn't be alive. Doctors say a lot of things shooting from the hip.

I'm still open to read objective studies that show these pumps or extractors remove enough venom to make any difference in outcome. By objective... I mean not done by the companies who sell the product.Until then, I'll stay away from these devices.
