I've played 2 rounds with it so far and putting has been great for me. I'm a streaky putter normally, one day make everything, next day 3 jack from 15' all over the place. I have a tendency to struggle with distance control. I'm coming from an Evnroll ER5 and I don't think I ever got used to the face.
I'm really liking the face/insert of the 7s and my distance control has been fantastic. I'm sure some of this is the honeymoon period, but so far this putter is amazing for me.
