Purchased this paper cutter after lingering for a long time and going over all other available for the same purpose. The prior review for this item made me choose this item. As for my rating, I am giving it a 4 star only for the fact that the quality check on this item is not immaculate - apart from that, it does everything that a good paper cutter is expected to do.The machine is easy to set up, if unsure check on youtube videos. I trimmed all my paperbacks with the cutter, at times I trimmed less than a millimeter from the sides. And it does the job perfectly. I have seen printing press trimming books from my childhood and I know the tricks of making a clean cut - like placing a thick cardstock at the bottom, holding the papers really tight while cutting etc. But that does not take away any credit from this cutter, its a heavy sturdy machine with a very optimal price.My machine's handle lock came bent, and that's why I said that this machine is not properly quality checked before packaging. But that is not a reason to return the product. I used a screwdriver to straighten it out and that fixed it. Also, I noticed that the blade alignment has gotten a little angled after 7 days of cutting. Not too worried about that because if you are handling this kind of machine you are expected to know how to set these things right - it will be a recurring thing.One thing to make sure is that the back support should not be tightened or loosened too much as it will break it. After handling it a few times I realized that it is something that just needs some optimal tightening and loosening. The marking on the scale are pretty accurate.
