Verbatim DVD+R DL (MKM01) QC

Just gotten a couple of these discs which burnt swell but I also noticed the overall build quality not as reassuring. Take a look at this pic to see the air gaps in the bonding of the layers of the disc.

The gaps can be most clearly seen on the clear plastic grab area as well as the inner edge near the recording surfaces -see the red circles.

As one bitten by defective stamped D9 original R1 DVDs (layer separation) eg. Contact, Apollo 13… I am a little wary about trusting the longevity of these Verbtaims for now. Is there any cause for concern?

Does the other DL disc makes exhibit such air gaps too?
