I was a little bit afraid to buy a shredder for this price but I am pleasantly surprised. I am not using it really daily but may be every third day and it works for already 3 months without single issue. It shreds credit card without any problems. I have not tried DVD yet. What ever you shred is shredded to such a small pieces that there is no way anybody can put it together. This is 100% secure system. I can strongly recommend it! Excellent product and perfect price!
