They work well for me in My location. First time I used them I had 4 coyotes staring at the caller. Im not too far from other ranches and feral cats are out and about. No doubt easy prey for Coyotes. Also on a Hunt with a buddy on BLM land, miles from any houses, that sound also brought a pair in. I have 3 foxpro sounds with kittens, and " Kitten cries" is the loudest to my ear, You cant go wrong having that sound in your caller. JMO.. Good luck.
