We purchased this through my company so I will not appear as a verified buyer. The device is actually quite good and works well. My problem with this is the description and feedback on data logging. They are very deceptive. This device shows the force value in real time, and later you can export the graph as an image file, which is useless for further processing. However, we could not find a way to continuously log/save data after a certain time interval. Instead, to collect discrete data points for export, the user must physically press the "Print" button on the front of the device (apparently you can also press the keyboard to do this). This is incredibly cumbersome and totally impractical if you need to constantly control the power. If anyone here knows how to log (and export) data continuously at a specified time interval, please let me know. Otherwise the sensor is very good. If you don't need data logging or just a few data points, this is the perfect sensor.
