I recently acquired a used Ping Anser 4 putter on Ebay after much research and really like the balance, weight, grip etc.
I took a few balls out and set up a cup at the end of our apartment hallway today.
The hallway is about 29 ft long so I set up some long putts at maybe 15-20 ft.
I was very happy with the accuracy I had and once I could somewhat estimate how hard to hit it I got alot of them very close.
I know that carpet putting is no substitute for actual greens but I was very excited about the results.
Just had to share that today.
Happy beginner indeed.
