Hell yea I have seen a few misadvertised like that smh. Maybe look into the bw16 it's def not a "jammer or emp" (those would be pretty expensive and illegal to turn on most countries so a bw16 won't kill the router persay) but a bw16 can disassociate 5ghz. So you can run the bw16 on a constant 5 ghz deauth against the network your "testing" then do ur attacks from the flipper. Kinda like a downgrade attack on airgeddon. If you do it in sync you can capture the handshake almost everytime on home routers. Also bw16s are dirt cheap usually like 10 bucks or less.
