I upgraded from a v2 to a v3. Miles better. It doesn't miss many shots and if you can remember to check the watch before you hit, tapping the tag on the watch will assure that you miss even fewer. My only issue is that I've now had to ship back two v3's because the cases cracked in the back. The second time the watch stopped working altogether. Customer service is superb and they've replaced the watch each time without complaint.
