## Questions & Answers

**Q: I'm looking for a thin plate. But this claims to be 0.02mm. Does somebody realise that this is 2x thinner than human hair??? Maybe it mean to be 0.2mm**
A: It could be a typo.  However, it is thin enough to fit into your phone case and serves for its purpose.

**Q: Are these plates large enough for MagSafe car mount surface coverage?**
A: Yes , the big ones . Different sizes . They are quite strong

**Q: Are these compatible with MagSafe car mounts?**
A: Yes.  Please be reminded that our products are just Metal Plate (Not Magnet).  Instead, MagSafe Car Mount should come with proper Magnet to suck our Metal Plate.  Hope this information help.

**Q: Are they compatible with Alexa auto ?**
A: No.  It doesn't compatible with Alexa Auto.  The whole idea of these Metal Plates are not for such purpose.
