To start with, I think this is a great product.. It does exactly what it says and is extremely accurate. I was looking for something that told me a bit about the way that I was playing the game and this small little device is able to do that every time. I have been able to modify my game to a very decent degree basis at the stats that I get from Flink. One of the best parts is that it is so compact that you hardly even notice that it is there after a few swings.. A great product and most recommended.
