Got me a couple of tipple packs of Primos, one mini and one regular, and, at first I couldn't get any sound, at all. Having read this thread, I understood it might not come right away, so I kept on. Less than ten minutes after I tried the first one, I started getting the sounds I wanted for cow, calf and bull bugle from all of them.
I agree about not practicing in the house. My "regime" though my grandson was playing with balloons and started getting after him, until she saw he had no balloons.
All I need to do, now, is fine tune my sounds and learn to get exactly what I want, when I want it.
I will, also, be practicing on the calf sounds for bear calling.
