Here are my first impressions using the Engo 2 heads up display sun glasses for running. They are very comfortable, and do as they say. No fancy stuff like showing who's calling, music playing, or taking photos or video. But it works with your smart watch Apple/Garmin, or you can use it with your phone. #trainwithengo #engoeyewear #eng02 #engo2 #headsupdisplay #running #runningglasses
