Review on 📀 Verbatim BD-R 25GB 16X Blu-ray Recordable Media Disc - 50 Pack Spindle: Store and Archive your Data with High Capacity and Ultra-High Speed by Philip Brianne

I bought this spindle a few months ago in addition to the single ply spindle. There were no problems with single-layer discs. However, when I tried to burn them, swollen bubbles kept appearing on the bottom of the disc. The first disc I burned was readable, but when I checked after having trouble with the others, I noticed that they also had blisters, just not as many. The next three I fired in a row were completely unusable and bubbles formed everywhere I tried to fire the 2nd layer (note there are none in the disc). Posting demonstration pictures including before and after pictures to show they weren't there until I tried to burn the disc. Result. I'm not sure if I got a bad batch or if they're just having compatibility issues with my drive, but I'm extremely dissatisfied and mostly upset because I didn't realize the drives were defective until it was too late to return them. Update: The next morning I decided to check it again since the first time I wrote I let the drive choose the speed assuming it wouldn't exceed the recommended maximum. I noticed that it burned at 8x instead of 6x. I accidentally forgot to put the speed on the first test again, but still got much better results with only a few bubbles on the outer edge. The remaining tests were almost error-free. I burned at 4x and as long as there was a bubble or two around the edges the disc was readable. Disc 6x performed similarly and both passed the test. I then tried burning at 2x (actually it was listed as 1x but it looked like it was running at 2x at the time of recording) and although it took forever to burn that disc the end result was flawless , there were ' no bubbles. All in all, I think the initial poor results may have been caused by a combination of the program writing faster than the drive, and possibly the drive heating up over time (because both DL discs written on day one , were fine). even at full speed, but each subsequent slice had some level of blistering). I'm using an LG drive and the xorriso Linux command line utility for burning.
