I did some quick looking around...while overall peeps are positive on the product, here are the cons I gleaned from a 4-5 reviews:
- Can’t keep stats
- Does NOT show distances centerline of fairway
- No indication that unit is fully charged
- Unit takes a while to initialize
- If you’re at a golf club with multiple courses in the area, sometimes it loads the wrong course
- No auto forward to the next hole
- It doesn’t give you an indication where bunker hazards are.
