I've used one for about 8 months. In general it works well, it's easy to set up at the range and to use with multiple firearms. It uses the sound of the shot to trigger the measurement, so you sometimes have to experiment with placement of the Labradar relative to the muzzle to ensure that it doesn't miss shots. It's a great unit for use at ranges where you don't have permission to set up in front of the firing line. The competing product in this case is the Magnetospeed, which is apparently more involved when switching among multiple firearms, but also has its fans. Any specific questions regarding the Labradar?
