Review on High Capacity RiData 50GB BD-R DL Dual-Layer Blu-Ray Writable 6x Disc 25pk - Long Lasting Storage Solution by Charles You

So I bought two of these spindles for 25 50GB discs. I've burned through the first spindle so far and started on the second. The very first disc gave me a sensitive key error and didn't complete the write process. I haven't had it since the DVD. But all other discs record normally and play/load normally in the BD player. I've found that Plex drives don't work. I don't know all of the discs from this manufacturer, whoever made them, but they were ALL bad and my BD player wouldn't play them. Switched to Ridata and am happy so far. I work through the 2nd spindle. The only thing is they are marked as 6x discs but I can only record at the max speed of 4x. I don't know why, but it doesn't matter.
