ECM Shot Mirror Overview An ideal tool for both diagnosing extraction issues with bottomless shots and simply enjoying the beauty of a well pulled shot, the ECM Shot Mirror is a simple and elegant solution to seeing your espresso up close. Weight is balanced between the base and the mirror and each half is mounted on a ball joint for easy manipulation to find the perfect angle. The mirror itself attaches to the stand magnetically for further assistance with positioning. No more bending down or catching errant spray caused by channeling!
