Review on AURSINC ESP8266 WiFi Deauther Watch V3 Development Board with OLED & Laser, Wearable Smartwatch - Attack/Control/Test Tool for DSTIKE NodeMCU by Zach Peterson

Yes, this device is really cool. In the wrong hands it can do many nefarious things, but for ethical hacking it can allow pentesters to do quick on-site testing for small business owners who think they have it all. With their written consent (bring the form with you) you can literally show them how easy it is to steal data from their systems and give them a hot incentive to hire you to strengthen their network and protect their data. Of course it's something of a sellout, but have you seen what's happening? Everyone is vulnerable!
