I got mine at Sams in OKC, there was no Costco at the time, 3 yrs ago, it is total change in life with the wifey,she is happy now ,amazing what you can hear. I worked as a steelworker for 30 + yrs.and have shot all my life, blind in both ears, Lol, I think the warranty was four yrs. I have taken one back and got brand new one, no charge, from what info I can get it's the little speakers that go out on them, any brand, they do cost . I don't put them on when working cattle or in really dusty stuff, you have to keep them really clean,all of them. Robert
