Great cheap calibrator

Great cheap calibrator. I was skeptical as this is the cheapest one out there. But it works fine. Does the job as advertised to calibrate my Smart 8 microphone.

Sturdy and Accurate

Shipping was fast. Ive compared this to other more expensive name brand calibrators and this one is just as accurate. I’ve also dropped it a ton of times.. still work just fine.
