I use rattling occasionally, it will work better if the buck-doe ratio is low and it works better if the timing is right, either late pre-rut or early post rut. I have both a Lohman rattle box, as well as real rattle antlers. I think the sound of the antlers is better, but the rattle box is a whole lot more convenient. If you want to do it, you need to try it, wait about 20 minutes, move on, and try again. It won't work most of the time, and definitely won't work if you give up.
Here in New Brunswick our buck-doe ratio is not favourable so rattling is not terribly effective, nor is it very popular as a technique.
