Not sure I could quantify the benefit to my game that my laser makes. Execution is still required.
At 55, my depth perception and eyesight isn't what it was 5-10 years ago. I can't see where my ball ends up most times when it's mor than 200 away. My Bushnell provides reassurance of the distance i have. I also have been using it to measure chips of more than 20 yards and this really has helped . Probably the best benefit I get is lasering the distance to hazards and to clear them and using it as binoculars to see areas of the green, slopes and where to best hit/miss shots.
That said a couple of the best iron shots I have hit this year wee when my battery died, I can think of 2 longer than 150 yards that I put within a foot and didn't use my laser.
