I have the Primos doe estrus call and it works great. I've use is blind calling mainly. When the moevement is slow, I'll turn it over 2-3 times and wait awhile. I normally wait at least 20-30 min before I use it again. I have had groups of does coming trotting in on alert very shortly after I used the call. Last season I had a young 8pt come running in a t break neck speed and stopped like he was looking for the doe. I have a buddy who has had similar results. However, it isn't a miracle cure. I have used it consistenly for the last 3 wks and have had a deer come into it, but that doesn't mean it never works. Good luck!
