Just bought this.
That's a pretty putter. FYI - the voice caddie sc200 is $50 off on Amazon right now: Amazon Voice Caddie SC200
I have been going back and forth on these and think I am going to go with the Voice Caddie. I have read all the reviews from Mevo, to Ernst, to the SC200. Mevo gives spin rate which is great, but you have to buy metallic dots to put on them. It also gives attack angle but the reviews say it is very inaccurate. Ernst is very hard to read the monitor. For what it does I really like the SC200. I like the fact that it has a game mode where you have to hit targeted distances. I think this is very valuable. Trackman has this mode and it was very valuable in straightening up my kids wedge game. Mevo and Ernst don't have this mode.
