I received this product very quickly and was very eager to see how accurate it was. After going through the set up (5-10 mins) I was connected to my iPhone and it was picking up my swing. The one problem with my swing was i tended to fade iron shots going left to right, as a result losing distance and accuracy. In a recent lesson i was told i was swiping across the ball to much putting a spin on it resulting in the fade/slice, I was told the pat of my swing had to be adjusted to try and combat that and improve it.
Rather than just being told this Golfsense actually showed me this in 3D and I could see where I was going wrong. After trying the technique I was told by my pro, I could see the difference in my swing and as a result was hitting it straighter and also with a nice draw.
Have to say even though it was a bit of an investment first of all, definitely worth it as i can actually visualise my swing as opposed to trying to imagine where I was going wrong. Go buy it!
