A:AnswerThis is the first time I’ve used the lubricated sheets. I’m shredding 20years of records and they (I’m using 2 shredders) are often on 4 hours/time. Although the red light comes on periodically indicating that the machines need a rest they don’t jam and the red light doesn’t stay on for too long (appx. 20 minutes). I’m really happy with the difference the sheets make. BTW, I use one in each machine about once a week.
