yes, i been a bit busy to test them.
but as promised here there are my conclusions:
to me they are average, nothing special.
first of all disc come in an old taiyo-like light grey bottom cakebox and properly sealed,
but theres a lack of the usual protective plastic dummy disc,
and i recieved the cake upside down.
so the first disc is ruined with smudges and scratched.
the center protective ring is not the usual foam one,
is thinner and of a cheapo material so it does not avoid the disc from touching the inner plastic top of the cake,
in case they come upsidedown like mine.
also discs are a bit more dusty than desirable for a sealed cake so take in mind that untill the first 5 or 6 discs are out you wont see a spotless one.
considering they are 2 recordable-sided flippers,
a bit more of care in packaging would be the desirable thing.
once the dusty first discs are put aside,
lets start with the first test.
ups… disc not recognized!..bad start.
restarted pc to fresh session.
now disc is recognized at last

cd speed 126.96.36.199 test
the first attempt results are pretty dissapointing with an overall quality of 93 an a group of spikes on the 160 pif range.
jitter bit high on 11 peak, trt doesnt look good either(img.2)
considering im used to pif peaks of max 8 and jitter no more than 10
im not too happy
so lets move on
cleaned opc cache and downloaded cdspeed 188.8.131.52
recorded a new disc
now results are a bit better(img.3)
pif a bit high with not good looking spikes of 88 at the end
but pi under the 500 range and overall quality 95
it starts to be at least acceptable.
the trt seems pretty similar… no improvement there (img.4)
now lets test it on a kprobe test at 4x
this looks fine to me (img.5)
45 peak a bit high but nothing to worry much about.
so i would not consider them totally crap :Z
as the results are mixed…
but unless you desperately need flippers better avoid them.
take notice that my cake was a bit dusty.
but even if they were mint condition i think probably had to use most of them for giveaways…
and also beign ritek is the BIG question mark of degradability.
we will see in 6 months.
