How to say ... This is the third of this model that I bought a few years. When they are used a lot, they take 2-3 years, sometimes longer, but at the price they are or I prefer to change, relatively easy procedure. Especially since the first was a SFA much more expensive, which did not hold much longer. So I prefer to use these shredders 'disposable' less than 100 euros, 80 even for the latter, which represents about 2.2 euros / month for 3 years ...
