I don't disagree this thing isn't the prettiest to look at. However, I think it serves a purpose and is actually a solid putter option depending on what you're looking for.
It is an interesting putter to say the least. I typically play with a newport/009 head shape and I'm a fairly good putter. The toughest thing to get used to with the Concept CX-01 is the insert feel. Other than that, I have been impressed with it. It's not as large as a typical mallet and there is way more "feel" with it outside of 8 feet than I have experienced with most mallets. The Concept has solid stability on shorter putts and it seems to help out on putts if you are one who has issues with getting handsy (as compared to a blade putter). The issue I've always had with larger mallet heads is the lack of feel on long putts. This thing actually provides you with feel similar to a blade but also reaaaaaly helps on those shorter putts when you want that extra forgiveness. Just my .02 on it. I'll be keeping mine in the rotation.
