Will the magnets damage my phone?

Our product is designed with safety in front of mind. We all use our phones daily, they are our babies and most are quite expensive! The last thing we wanted to do was damage these products. Our rare-earth magnets have a rating of N50, the perfect strength to not interfere with wireless charging and still give a strong, secure hold. You should not be worried as the magnets in the SnapMount will not have any negative or damaging effects on your smartphone. Only industrial strength magnets can damage smartphones that we use today.

“there will be no issues at all with the magnets that your phone is likely to come into contact with during everyday use such as those in magnetic cases or cradles or on your purse or handbag”
