Nextorch has released an interesting oddity, the ND30B. This appears to be an update of their recently-released ND30. If you would like a flashbang (and yes, you can get civilian versions of them), but don’t want something quite that violent, then perhaps this type of device is for you. It boasts a 1100 lumen flashing strobe and 130db of noise.
Though flashbangs are widely used, they aren’t without their risks. It appears this device should be completely safe.
I don’t know if this is a useful tool or simply a novelty. You can watch the video on the ND30 and decide for yourself.
