Somehow, I think in the course of all my freebie hunting, I won one of these! It came in the mail yesterday.
Today I used it to vacuum seal some chicken thighs, and it worked pretty well. It's just a little hand pump, and you stick it to a spot on the bag and pump the air out. It takes a few tries to get the hang of it.
It worked pretty well with the chicken, although it didn't get every single bit of air out from the little crevices between the pieces of meat. But it worked much better than my normal method of trying to squeeze air out with my hands. It doesn't work as well as my mom's foodsaver, but I think it'll work for me because I just have a small freezer and usually use things before they get freezer burned. This might make them last longer.
It wouldn't work with anything liquidy, because the bag and pump have to be flat against a hard surface for the pump to work.
You do need a special type of bag to go with the pump. I don't know how expensive the bags are because a few came with the pump, but I'm sure they're not cheap since this is a pretty new product. I do have a coupon for them.
