I used one last season. I hunted in several states and with only one season, it's tough to make a determination of how good it really is. Here's what I found. If agroup of hens and gobblers are coming in, the gobbers seem to come in first to challenge B-Mobile. If it'sa lone tom, they seem to hang, or not come in at all. I think they work, but just like everything else, in the right situation.
