The Pyrex #4980-PACKRS Narrow Mouth Erlenmeyer Flask Set has received generally positive feedback from customers who appreciate the quality and durability associated with the Pyrex brand.

Overall, the Pyrex Erlenmeyer Flask Set is praised for its quality materials and robust Construction, making it a worthwhile investment over less expensive options. However, Consumers should be aware of potential issues with the stoppers that accompany the flasks. **
