Review: Rated ultimate vacuum of 5 Pa is bogus, actually is about 40 Pa - Seems to work, rated ultimate vacuum of 5 Pa is completely bogus, I measure about 300 microns with a new Testo 552 digital vacuum gauge, which is about 40 Pa. For most uses, 300 microns is probably sufficient. The price is certainly attractive, don't know about how it might last. Mine was part of a kit with a 3 gallon glass top chamber.
