Review on 1 High-Quality Glass Hydrometer Testing Jar by Dee Scott

TLDR: The bottom is paper thin and breaks very easily just by touching the floating hydrometer! Mine arrived yesterday so I filled it with a sample from an elementary school and dropped my hydrometer - this beer is almost done (1.005) so the hydrometer went straight to the floor and then the beer suddenly spread all over my counter off - a hovering (!) Areometer sinks to the bottom and knocks through the bottom! After cleaning everything, I inspected it and the thickness of the bottom is exceptionally thin (see photo).
