Phax, don't discount the free Beginners putter. If you need faster finger reactions, then this club can help immensely. There is some apparent inconsistency when you need to use the 60 and 150ft scale but with practice on approaches, you may find that that becomes rare and also that you get used to it and accommodate it in time. This putter also takes all the stress out of trying for a ding, if dinging is your method of choice, in that the meter movement is smooth and even throughout its travel and does not speed up as it approaches the ding marker.
The author would like to make clear that other putters are available with similar looking attributes, better colours, a negative number financial outlay and that all comparisons may or may not be exclusive to one or more persons. Its just they are the scrapings from the bottom of a dirty barrel in comparison is all.
Also, other learned opinions are available. Bite me.
