I've been looking for a shredder that destroys CD's for some time and came across this yesterday in Sainsburys.
It's quite a big/meaty machine approx 35cm tall x 32cm wide x 21cm deep
There are 3 separate slots on the machine:
1) Paper (cross cut 4x36mm)
2) Credit cards (cross cut 4x36mm)
3) CD/DVD (strip cut 15mm)
Large mesh basket
Auto/on off reverse
