We are replacing our old paper trimmer with this one. Our old one was smaller, all-plastic, and had a fixed blade. It would only cut one sheet at a time reliably. This new trimmer is far nicer. It is metal base, heavy plastic end caps, and a titanium roller blade. It accurately cuts several sheets at once and will trim paper up to 12 inches long (or wide). The base is marked for several different paper dimensions, mostly Metric. It precisely trims your photos, documents, just about anything. So glad we got this excellent trimmer.
