Right out of the box, this was easy to setup and use. I was had an item laminated within 10 minutes of unboxing it. Simple setup, simple to use. The instructions were clear and to the point. There are 2 heat settings on the unit, one is 3 mil and the other is 10 mil. You use 3 mil for regular paper and 10 mil is for thick paper like cardstock and business cards. The only issue I did see what that the Power button sticker was not on properly, it was off-center so it did not adhease they way it needed to. No biggie, I reseated it and it is fine. I laminated a 8.5x11 piece of paper and used the big sleeves. Went through in under a minute. Came out and was not hot to the touch. Sealed great AND was fast. Very satisified with this unit, and I have gone through several laminators.
