are these any good / waste of time

downloaded Rugers I Hunt & ported it thru a Bluetooth speaker cube set it outside and drove the squirrels crazy for awhile. Looking forward to trying it out at the lease. Some peeps posted on our Facebook page this weekend that the yotes are raising hell around the camp. they are free for a few calls or $2 for 600 calls
