I'm now coming to the end of my 100 pack and I've had about 1 in 5 failures. Failure to verify and sometimes the burner fails to recognise. Tried on three different burners and similar results. I would say avoid, in spite of the brand name.
There's no point in complaining to TDK if you find these discs to be in anyway faulty. They sold the CD-R/DVD-R side of the business three or four years ago to Imation. Previously the products were manufactured in the E.U. but are now often sourced from India. So it's a case of buyer beware.
