its not a bad machine for the price, there are definitely a few design flaws tho.
If you laminate without a sled, and your laminate is wider than your media, the laminate will stick to the rear deck of the machine as it feeds out. That gets to be a headache, I ended up taking the rear deck off, lot fewer problems, and easier to cut off the graphic without wasting a foot of lam every time. (my longest print runs are 5' so it adds up fast )
Also, silvering is almost inevitable. there is no speed control on this machine, just stop and go. the silvering eventually will go away after a day laying out, but its an annoyance.
As CS said, budget at least a half roll of lam to learn how the machine sets up and tracks. It may seem cut and dry but you'll learn quite quick that if its not tracking straight, you'll have wrinkles in no time flat.
