I tried using Connex tags on 4 different rounds, but found them unusable. Having to leave your phone unlocked is problematic, because in my pocket the phone begins opening random apps as it detects contact with the liner of my pockets. I forgot to tag a few shots, and couldn't get the manual function to work. The gps was showing my ball in very odd locations, nowhere near the course a few times. Also, my putter doesn't accept the tag, so for the first 3 rounds I tried doing it manually, but the app was very non-responsive to placing the putt location. On round 4 I kept the putter tag in my pocket and that worked for a while, until the app crashed. The app crashed on me mid-round each time I played, and when I restarted it it was stuck in a loop on hole 1, and I couldn't advance to the hole I was on. I eventually had to clear the cache when i got home and delete the round in progress. I really wanted this to work, but I returned them because it was frustrating and time consuming on the course.
