Each of the 5 piece's in This Set is of Good Quality for it's Function. These are Not For Rapid High Temperatures, But Great For To Many to Count Home Learning Experimental Extractions. They Can Be Heated "But" it's best to heat Slower then Their Expensive Counterparts. These are well worth the money spent on them. I'm Really Proud to Add These to My Kit.

The packaging was questionable, all the boxes were opened before I got to open it, no packaging material and flimsy cardboard, the delivery man "tossed" the package onto my front door.. fortunately it was fine. Glass has some scratches near the top but overall they look nice

Quality of glass appears to be as good as pyrex or kimax at a fraction of the cost. One piece in a set of beakers had some partial off kilter graduations. But measurement accuracy is still possible. Otherwise every other piece was perfect!
