Why oh why is this stuff not marketed better? I found out about it when I was ordering a new shredder (it came up in the product search), my old one was a cheapie and really struggling, it was getting out of puff with two sheets at a time. I ordered both the shredder and the oil. When the oil arrived I thought I would try it on my old shredder. A few drops in the slot has given it a completely new lease of life. My new shredder, while perfectly fine (and a fairly expensive one) is still in the box. So..... the moral of this story: try some of this stuff if you think your shredder is on its last legs. From what I know now, shredders' should be oiled regularly in any case, so if this doesn't sort your old shredder out, you've lost nothing, you'll need the oil for the new shredder. If you were planning on going for a decent one, like me; who knows, you could save yourself 50 quid
