It works, and that's all that's good about it
This thing was clearly designed by an idiot but it works. It's tedious to use, it hurts, the tweezers that come with it are garbage, and the buzzer is loud (but luckily it can be removed from the circuit without breaking it). Honestly you could probably just attack the probe directly to a 9v and it'd work just as well if not better. But I digress, the device does indeed work.
