any comments on demagnitizing cds ?

i have a furutech demagnetizer, model rd2. i saw one selling on audiogon recently and it reminded me that is gathering dust on the shelf.

i used it a few times and found that cds which i found annoying to my ears sounded more annoying after an application with the rd2.

when i used it with other cds, i heard less noise, but the result was too much detail.

does anyone have favorable results demagnetizing cds ?
