That exact same cutter came in the mail a few days ago. I bought mine from ebay, it was roughly the same price. I dont know why I went in that direction.
I fell in love with this thing on the first cut. It has a sleeve or a tab where 120 or 35mm film slides into to prevent it from pivoting. The semi-transparent part is great over a lightbox, I can see exactly where I want to cut the film. The whole thing is really light so keep the rubber stops on the bottom clean, they work really well until you place them over a dusty area then it just slides all over the place when making a cut.
The one minor thing I dont like are the rolling rubber advance wheels inside. I cut my negatives to fit in a sleeve so they get cut in 6 frames for 35mm or 3 frames for 120 so the little rollers end up slowing me down when I want to pull a few frames of film after a cut. They do hold the film in place but I think the same effect can be achieved by just holding the edges of the film while you cut. But since this is designed to film from framing it makes since to carefully inch out each frame before cutting.
But Im told they wear out after some usage. Looks like I better cut more film to get it just the way I like.
Anyway, this thing is fantastic. It makes perfect straight cuts. As careful as I was with scissors vertical lines wernt always very vertical.
Best 30 dollars I ever spent, until something even better that cost 30 dollars comes along.
