I chose this one because
(a) it takes nice thick 250 micron(2 x 125) pouches
(b) it does A3 right down to business card size and
(c) the price was fantastic (it was not much more than the cheapest A4 laminator!)
It arrived in 3 days and it was well but not overly packaged, which was excellent. The seller also sent me an email, advising me what date and time the delivery would take place, which was also excellent. And never having used a laminator before in my life, I opened the box, read the instructions and successfully laminated several A6 documents in no time at all!!! And each one came out perfectly smooth and even :-) I also found that you could feed 2 x A6 pouches into it at the same time, which obviously halves the time taken to laminate them :-)
And although I didn't notice it in the technical details or description, it definitely does hot AND cold laminating! Apparently, you have to use specific "cold laminating pouches" for cold laminating. But as I had already purchased some 250 micron "hot" ones, I will just use the hot lamination for now... but it's still nice that the option is there in case I ever want to cold laminate a delicate object.
Bottom line is that yes, I would definitely recommend this product and this seller to anyone. So if you are after a laminator, do not hestitate to buy one!
