I picked some of these up yesterday and am very pleased with the results! Highly recommended even if they are a little pricey.
Burned in BenQ 1650 BCHC @ 12X, SB On, WOPC OFF.
The Maxell 4X I picked up from Currys turned out to be YUDEN000 T01. All in all, a good days shopping!
The T01 was also burned in the BenQ, SB On, WOPC Off.
