So glad I got this, awesome phone holder

Very strong magnet. Basically, they give you a metal sheet that you put in your phone case that you use to magnet-stick it to this mount on your car.  The metal sheet is thin and soft, so it won't scratch your phone or add bulk. There is even adhesive if you don't have a case.  Magnet is super strong and holds the phone on tightly and I've never had it fall off.  I love this thing.  Makes driving so much more safe and I don't have to hold on to the phone and distract myself.

Tip: If already using a case, don't remove the adhesive sticker, so if you switch cases next time, you can still reuse it!  Great product!
