I want to buy a wifi/bluetooth jammer but i dont know what is the best choice.

As you could guess, i am completely new to all things hacking and gadgets. I just want somthing fun to mess around witn and live out my watchdogs 2 dream. Ive seen some like the BLE shark nano and the esp32-div V2 but if anyone has any other/better beginner friendly gadgets that i should look into that would be the best
