I have made alot of blinds mostly for archery antelope on water holes. 4 years ago I bought a double bull. I was concerned with a pop upbecause ofthe winds that we have here. they hold up extremely well for what I do. I have broken 2 of the poles so far one from a wind storm and once was my lack of know how when trying to set it up. When I talked to the boys at Primos to see if I could buy new ones they told me I couldnt but if I gave them my address they would ship me some new ones for postage. To me that is service... I have friends here that have ameristep. They tend to go through more poles and get charged for parts everytime. They cost more but for me it is worth the extra overtime money needed to purchase them.
