Comments about Acer XP177-001:Acer CB4 Putter:

I discovered the center line groove was off line between 1-2 degrees after a few weeks of use and what I believed was a slight pull. I used a metal file to regroove the center line groove and also had to repaint it. It came out serviceable, but not something I would want to ordinarily do. I also found the factory grip to be somewhat small for old hands, and replaced it with a midsize which seemed to work much better for feel. I wish the manufacturers of these putter heads would exercise better quality control on the alignment and aiming aids, I've seen heads from various overseas factors with these problems before. Even if they are at a low price point, in this case a good design was somewht compromised by average to poor quality. Next time I discover a flaw like this I'll simply return the item regardless of a few weeks of use. I like the design, but my recommendation comes with a qualification to check the finished product closely for accuracy.
