This thing just works. I use it for sorting projectiles for reloading. It is also very good for checking charges for handgun reloading. It can operate both with a battery and using the AC power adapter. This unit is a very good value overall.
Pros: Easy to use; Very accurate; Easy recalibration
Cons: Recalibrate often
