Yes I have, and yes I would.
I recently purchased some of these from KMart on sale $7 for a pack of 20 (15 plus 5 free). The date code on these are TG001133 and they are branded Fuji 8x +R's. These disk or either bad or just plain crap. I ran some quality checks after burning at 8x speed and all results were "BAD" and with PIE's as high as 100. I actually get better results from the "Value" 4x ran at 8x.
Like I said, maybe just a bad batch of disk, but I stear clear of Fuji Brand because of it.
Just my 2 cents.
