I upgraded for ST+ and it is a game changer. No shot delay is a good feeling - but the features that really make a difference is being able to play while having the view software open. I setup 2 TVs on the wall, I use one of them for all the metrics and the other one to show impact. Having the exact image of the strike + the club data (especially AoA ) brings the game to another level for me. I was disapointed when I upgraded from ST to ST+ but now I'm happy with the Eye XO2. I haven't played much with it yet but setup went fine and it seems to be working properly. I've had 3-4 misreads with driver/3W last night when I played a round and I'm not sure if that was due to low lightning or if I was too close to the edge of the hitting zone (I did hear the "ready beep" before hitting) so that's the only thing I have to look into. Putting and chipping is better than with ST.
As always Rain or shine golf were able to help me and answer all of my questions before I went through with the order. Getting the unit took a long time but it was not their fault and they were helpful throughout the whole process.
