Works great, consistently for about 1.5 yrs now. Only hiccup was an OS update about a year back, but Garmin fixed it fast and haven't had problems since. I like the new data fields, but they take a bit of time to enter fully if doing load development. For factory ammo, it's very useful as is, since one you enter data at a given weight, you get it by default. But extra steps for load developers to accurately track. More data, but more tiny keypad data entry.

The chrono companion app that keeps track of shot velocities, avg, standard deviation, min/max, and bullet weight, and energy(if you enter bullet weight). Recently added profiles for firearms and load data. Can export to a file or to the cloud. The new additions are good. If they just added the ability to take a picture of your target and add group size to a session it would be an extremely useful app.

Every time there is a major update, my Xero C1 has to be re-paired with my phone. When that happens, the notes added to sessions are lost. I have dozens of recorded sessions but I no longer know what batch of ammo they are from. I've had to start exporting data to Excel as soon as I record it. Notes and other user-entered data needs to be kept!
