Query: BEWARE! Will not work in many burners!

Amazon doesn't state this, but this will NOT work in any burners which are slower than 16x burn speed! I ended up eating eight bucks on shipping as a result. I'm sure the discs are quality, Verbatim's never let me down, but buyer beware -- don't get these if you don't have a high speed drive, they'll be useless to you!
