FINALLY a cost effective and safe solution to navigating on your bike. Phone operates normally through the clear cover. Sitting upright next to the mirror it's easy and safe to check without looking down. Air flow around it keeps the phone cool too which has always been an issue with flat mounted options. Certainly water resistant not sure about proof. Two sizes available. Every Grab and Uber bike should have one of these for a start and we all might live longer. 250K VND $11 USD
