I was allowed to test the Peach PS100-00 Shredders Service Kit with oil paper commissioned by Testeberichte.reviews who provided me with the paper free of charge. Unlike other testers, I tested the oil paper with the 19 euro instrument from. Peach and am satisfied with the effectiveness and ease of use. I think the idea, with oil just to have a welded packets pass through the shredder to maintain this, in itself times awesome. You can therefore go through the packet, then the shredder 10- 20sec. run backwards and already the cutter is practically oiled. Should order to use the kit regularly to prolong the intervals specified but, otherwise sin 8 Euro violently for 12 kits.
