I bought this in part because all the inexpensive name brand (e.g. Scotch) laminators no longer have guides; this is somehow reserved for high-end models. This doesn't have guides either, but at least it is wide enough that alignment isn't super critical for letter-size paper. It's even wide enough for 11x17 with imperfect alignment.
It heats up a bit faster than my old, dead Scotch laminator.
As others have noted, on the unit I received, there is no heat warning sticker on the (removable) lid over the rollers as pictured, and it gets hot enough to burn. This is basically like a conveyor toaster with heating elements that heat up two of the four rollers instead of toast, and the cover is immediately above the top heating element. So of course it gets hot.
The meter doesn't display the actual temperature; it displays the temperature set by the knob, which is also labeled. The documentation says to keep it running with heat turned off to cool down until it reaches 80° (presumably C). However, even if the meter displayed actual temperature, it wouldn't help much, because the meter reads down only to 100°C — there's no way to know when it's really cool enough. So, run it for a while? Five minutes? Ten? Who knows...
The documentation is relatively useless. In particular, it has inconsistent suggestions for heat settings for different film thicknesses. I found an online reference in °F and converted it to °C:
3 mil: 135°C
5 mil: 140°C
7 mil: 150°C
10 mil: 170°C
So far I've tested only 3 mil but it worked fine set to 135°C.
Ultimately, knowing all this I would probably buy it again, but I don't have young children who can't be trusted around hot appliances either.
