Potentially good product but not a recommended buy yet...
The product itself is well made and everything it offers for the price is fantastic. With that being said, the software itself is wildly inaccurate. The main sell of the product aside from the simulation is the ability to track club path, face angle, and club speed. The issue is with the calibration of the sensor.
In an ideal world the software would have a calibration setting which would compensate for any rotational offset between the club face at square and the sensor. The system would then be able to tell when a player is taking a shot with an open or closed club face at address. When calibrated the sensor would also know the standard shaft plane so that when a specialty shot is played using a different shaft lean, the system could understand and represent that with data.
At bare minimum, this system needs to be able to calibrate such that it knows what “square” is at address.
Until that happens, I wouldn’t recommend this product for any kind of game improvement investment. For now it’s just a neat toy.
