they look like solid products, but, if you can make them yourself, it’s better. Never tested them tho. Also, Seytonic makes some really cool alternatives to the rubber duckie.
Ive bought a few of their things and it depends. Like with the wifi pineapple, i dont think you need it, and the rubber ducky there is heaps of alternatives and building your own seems better. But with things like the shark jack and packet squirrel, I do think that its worth it.
I would if they had some laptops or microPC’s with built in wifi-chipsets which support useful modifications and preferably amd cpu/gpu for free drivers. BTW: do you have any suggestions where i can find those?
