Title: doesn't work
Review: Very poor, stupid design. It does not generate enough pressure. It slips, damaging the jar top as it rotates against it. Then, it slips off the lid entirely, hurting your hand, since you have to press down very hard to get any traction at all. I still use it sometimes, but either the rubber pad or hot water method really work at least as well. I look forward to tossing it as soon as I find a decent gadget.
