Take away info: 3-year warranty on cutter.
Office Depot item #405935: Ativa DQ83M Diamond-Cut Shredder (mine show model ...Mn. It has a 1-year warranty for product, BUT ALSO a 3-year warranty for the "cutting cylinders". Call 1-877-777-HELP; www.ativaproducts.com
I called 12-29-2010. Rep had difficulty finding product, put me on hold, found it. Said prod only has 1-yr w (per Office Depot online, this is all that is given as to info); but I said, no, 3-yr on cutter. I held again, rep researched and agreed. I took a case number and tried rep's troubleshooting suggestion: I put 3-in-1 oil (veg oil suggested by rep too) on the jammed shredded paper (machine still would go in reverse BTW); I let it soak 5 mins, removed paper, tried shredding, and paper jammed again. No replacement parts are avl. I called again, gave case number. Rep suggested I oil the cutter now that paper was removed. I said cutters are oiled from removing paper. I was put on hold, only a short while.
Good outcome thus far: I was given fax number and instructions to receive gift card in 6-8 weeks upon their receipt of my fax (to 1-888-561-0785) of case number, name (first and last), mailing address, and copy of the receipt.
What I learned: Do the maintenance oiling monthly or more if needed! Try to buy a shredder that is beyond my shred needs, e.g., a 10-sheet cutter but use it only up to 8 pages. Try to buy a shredder that has replacement parts.
The price of the Ativa in 2008 was $40 ($30 instant savings taken at the register), and it didn't get daily or regular use.
Good product support on this Ativa product. Glad I saved my manual and receipt!!
