I used this laminator for two months during which time I laminated about 80 sheets of A4. Initially it was fine except for the fact that unlike my previous Pavo it was unable to cope reliably with paper or card over about 150gsm. My experience with 200gsm card and various makes and thickness of pouches was that there was a period of about two minutes starting shortly after the green 'ready' light came on, enough to do two sheets, during which time laminating was successful. Otherwise it would produce bubbles and patches, even when the light was on, which could not always be eradicated by passing the work though the machine again. After about 6 weeks these problems then began to arise irrespective of what was being laminated. The machine was spoiling a lot of the work. Almost certainly this is because it was failing to work consistently hot enough. I had no choice but to abandon it. This is a very inexpensive laminator and could be fine for anyone with only the occasional laminating to do involving paper or photos. However, it might not be built to last!
