Instant feedback if your putt is off line. I have seen a dramatic increase in my putting in the short three weeks I have used this. Hopefully a winter of using this will produce great results in the spring.So far I have only used inside on carpet. Only issue I see is that because of the thickness of the device it is possible to catch the edge while putting. To solve this I laid a thin piece of wood behind the device. This prevents your putter catching the edge.
