I have had two problems with my double matrix 360. One of my rods broke after leaving the blind out in some really high winds. I called them and told them one of my rods broke. They didnt ask for any receipt and sent me four new rods.
Now just last year the zipper broke on it, I think more from my kids messing with it than anything. They sent me out a new zipper no questions asked, and a local tent and awning company put it in for cheap.
I dont know if Primos is required to honor Double Bull warranties or not with the sale of the company, but they have been nothing but helpful to me when I have had any problems with my blind. I would recommend them to anyone I know!! There just arent many companies around like that anymore...
