It seems a bit odd to compare a 3D printed product with "jerry-rigged" devices.
It looks nice but the form factor somewhat looks like what might just be an ESP32 + directional antenna, is the selling point the integration and behaviour profiles of known malicious APs here? Without details and "contact us" pricing I'm really not sure what to make of this. But I guess if the price is low enough it's nicer than putting one together yourself.
