you need to set it up so its a footswitch, then only use it for like 0.5 seconds when you turn a corner and see an enemy.
I made one for less than €5 with stuff from an electronics store.
It gets incredibly boring after like 2 games of doing it, so i dont even bother now. But you should only use it in very small bursts, less than half a second. Its enough to get the adavantage u need to kill anyone
This is me, using it VERY Excessivly, just to show my friends what it could do.
I didnt even use my own account for it, I set up a dummy account
Edit:Just after the last kill it host migrated, you can rarely prevent host migration by flicking the lag switch repeatedly while its trying to migrate but it mostly ends the liobby.
Also If you are host in a lobby (check by Printing <space>, 1 , <space>

(if the spaces show you are host) when it says migrating host in the lobby screen keep flicking the lag switch and you remain host(more often than not)
Also you could try setting up an account in 'oman', im in ireland and i have hosted games in oman, but u need a good connection, I have a 30ms ping to dublin and download 15mbs, upload 2mbs
