They should be better than Princo by a mile, or a few kilometers at least.
Seriously, though, from the few scans I have seen of Optodisc RW media, I’d say it’s okay media. There is some better media [like that by Verbatim, Ricoh, and Sony], but a lot of the discs I see are around the same quality.
If you’ve already written to one, do a disc quality scan and a transfer rate test, and post the results.
[in case you need a refresher course]
To do the Transfer Rate Test, make sure you are in the Benchmark tab, click on Run Test, and select Transfer Rate.
To do the Disc Quality Scan, select the Disc Quality tab, make sure your speed is set to 4x [4x and 8x are forum standard scanning speeds, and the LiteOn A1 series doesn’t always like 8x], and press start.
