Arrived on time and well protected in its custom fit packaging

Have not used it yet, but it appears well manufactured and looks to be fit for the intended purpose.

Worth many times more than the price

I'm a trained chemist, but it's been a while since I dabbled and I needed a new sep funnel. Frankly, for the price (~$60) I thought I would get crap. This funnel is not crap at all. I wish I had bought 3. Actually, now as I write this, I'm going to clear them out. If they restock, do yourself a favor and grab one. I can also confirm that it is most definitely borosilicate.

hole in PTFE does not line up with hole in glass.

The PTFE stopcock seems to have been perforated in the wrong place, or else a piece of glass extrusion is blocking it. Only about a third of the hole in PTFE is available for flow when fully opened - Which sucks for viscous liquids.This item seems to have missed a quality check, assuming they do quality checks...
