OK, i admit... i bought these based on price. Bad move.The shipment arrived & the plastic bubble over the spindle & CD's was broken, bad sign.When i started to burn the mix discs i send for xmas presents, the burn process would stop halfway thru & the Mac would spit the disc out.I tried burning on my Dell laptop & the same thing would happen.Tried >10% of the spindle & failed every time.Bought a cheap 5 pak of discs from walmart to test & they burned flawlessly.Bought a 30 stack of Staples CD-R blanks & burned them all w/o incident.I'm debating whether to pay the shipping back to Maxell for replacement, or just toss'm & chalk it up to experience.
