I've owned Sears tools for about 25 years. I've replaced and returned their tools in PA and CO. Neither store had a problem. I have to admit back in '76 when my Dad bought me my first 52 piece tool set that the reason he paid $26 for them was because they had the WARRANTY they still have today.
I've had worst problems trying to get my king size mattress repaired/replaced under its warranty! It was 'touted' to last 8-10 years. We ended up trashing it after 4 years! I'll never buy a Heritage mattress again!
