What Customers Are Saying

Customers praise this tool for cleanly cutting acrylic, plexiglass, and polycarbonate sheets, with many noting it cuts "like butter" and makes clean lines when used correctly with a straightedge and firm pressure. Most find it affordable and effective for light diffusers and poster frames. However, a significant portion report durability concerns, describing the tool as flimsy with blades breaking on first use or plastic bodies snapping under pressure. Several advise buying something sturdier, noting it won't last long despite initial performance. Overall, reviewers recommend it for occasional projects if used with proper technique, though durability remains a consistent frustration.

Follow Directions to Get a Clean Cut

Would Recommend

I used this to cut a .08 in piece of plexiglass. Per instructions, you really have to make numerous passes with this cutter to cut deeply enough (states needs to be halfway though) to the point where the plexiglass will snap apart cleanly when bent. Otherwise I found that if you cut a line that is not uniformly deep enough it will break unevenly. You also need to put your weight on it to make deep cuts. Follow directions and it works as advertised.

Started off great and seemed like it was working well, but the blade ended up snapping trying to cut polycarbonate

Not working

Would Not Recommend

I haven’t been able to get this to work yet. I’m not sure if maybe I’m not using enough force, but it will not cut.

Didn't use this item

Would Not Recommend

I would've rated this as N/A, but it wasn't an option. I ended up not needing this and didn't even open it, so I plan to return it.
