it works...i actually think its built well... u can switch from the grunt to the snort wheeze fast, its soft rubber so no noise if you bump it. and it stays out of your way on your arm.....i only payed $17 at dicks for mine and if you want higher pitched grunts just pop the black rubber tube off the end of the green body of the call...u can deepen the sound a tad with your hand that way....
