Hmmm... I've read the instructions and I'm still not sure: What advantage does this device give you over just sticking the pump/vacuum cleaner hose in the end of the bag, sealing the bag to the hose with an o-ring or good rubber band, and tying it off after the air is out? What am I missing?

Actually, I feel like an idiot now for not trying something like this earlier. I really had to put the knees (and butt) into squishing those blankets down with the whoopee cushion bags, guess I couldn't envision a thin garbage bag as being able to keep them squished. But if one can keep the air out, then... Should work.

I might have to experiment with the ol' vacuum cleaner when I get home tonight. -mark
