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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent quality and presentation ⭐️ *by C***M on 16 April 2026* This product is excellent.
