Pretty good for price
Few little nic's/scratches but seems air tight nonetheless. Also slight crack at the tip of the barbed glass where the vacuum hose connects. If not for these few yet very minor from what I can tell so far problems would be 5 stars if not for the extreamly low cost would have been 2or3 stars

#8 stopper
Just received it. Haven't heated, or dropped, it yet. The interior diameter of the opening is 1 3/8 in, or 34.9 mm, which means a #8 stopper should work.No visible bubbles or deformations.

Quality glass.
On second day I had it, I dropped from about 4-5 foot and all it did was bounce. It didn't crack or chip anywhere. Ive used several times since then under pressure and vacuum and it's just fine. Well made and very thick glass and came a day early.

Excellent Quality Products.
StonyLab glassware (and their other products) have all been superior quality. The glassware is durable and ground fittings are precise. I give them my highest rating and will continue purchasing and using their labware.
