Professional Glass Quality A+++
Excellent packaging, Quality thick glass, for professionnel lab, high heat resistant since its for hot filtration during recrystallization. A+++ I recommend it. (Remember to buy a rubber seal to get good suction during vacuum for best results)

Does what i's supposed to.
Does what it's designed for but I got the feeling the tubing attached could have come off easier. I think this is due to the grooves on the connector being a little sharp. 4* out of 5* for a good product.
