Review: Most worked great! - The 35mm, the two 30mm, and the 15mm worked great! The 25mm, the 20mm, and the 10mm didn't work well, as they seemed unbalanced, so they were noisy and it was very hard to get them to work. I am using these with the INTLLAB Magnetic Stirrer.
Review: nice - good

## Questions & Answers

**Q: What is the max temp you can heat to ?**
A: Melting point for PTFE (Teflon) is 326 C or 620 F.  You want to stay at the safe side of that with a good margin. The magnet itself his much higher, but should be covered by the encapsulation at all times.

**Q: Incluye las pinzas  y el estuche? viene como en la imagen? gracias**
A: En el que yo compré no incluía pinzas ni estuche

**Q: What's the difference of type b vs. type c?**
A: Looks like the type b’s have a ring around the center to help it spin easier

### ⭐⭐⭐⭐⭐ A nice case to keep them all together.
*by T***C on October 3, 2020*

I bought these to replace my LOST set... And the LOST ones turned up right AFTER two uses of the new ones. These work very well for me and have a nice little case. SO... I hope not to lose any of these.
