I finally tried the Pump n' Seal. We watched the video first (it's on their website too) & then found a couple jars to seal. It works really well. Kinda fun too.
First you take the push pin & poke a hole in the lid. Then place a small yellow tab over it & place the Pump n' Seal over it. Just pump away. It only take a little pumping to seal the jar depending on how much air is in the container. The one thing we never seem to use up fast enough is salsa. So we sealed it & put it back in the fridge. I think I will be having fun the next few days looking for stuff to seal. It also comes with a hose so you can seal plastic bags. We haven't tried that yet, but when we do, I'll let you know how it works.
So... I give it an A+
