What to know before buying
Listing details to confirm
Listing details are inconsistent: the title says 12-sheet, the model field says “8 Blatt”, and supplied dimensions differ between 32.5D x 19.5W x 40H centimetres and 32.1×20×46.5cm. The listed 12-sheet capacity, P-4 security and 5x20mm particle size are manufacturer claims. Confirm the exact model and dimensions in the selected listing. The manufacturer says to cool the machine for more than 40 minutes after overheat protection activates and not to shred newspapers, thick cards, cardboard or metal credit cards.

Customer feedback describes the shredder as capable and praises its bin capacity, with reports of handling up to twelve sheets. Experiences are mixed on speed, noise, jamming and overheating, and durability is a concern in some feedback. That makes the short claimed five-minute run and stated cooling requirement especially relevant for frequent or prolonged use. The aggregate ratings lean positive overall, but do not resolve those differing experiences.
Positive themes
- Customers praise shredding performance and the capacity of the bin.
Negative themes
- Durability concerns are reported, including accounts of breakdown after relatively little use.
Mixed feedback
- Feedback varies on speed and noise, and on whether jamming or overheating occurs.
