Something with the DSCosmetic handles... they seem all electropolished, which gives even their knurled handles a slightly slippery feel. Most blatantly felt when comparing the Razorock Super Knurl with their THS (THT for the titanium version) dubbed handle copy.
The second thing, almost all I got had black gunk on the threads. I am not sure if this residue is leftover from machining or if it was supposed some form of lubricant. The latest Blackland Dart copy called Roman Column worked out nicely, though. They seem to make huge batches, I would suggest if there is no strong preference for a particular handle to go with the head only or pick one of their latest handle designs.
For the R41 copy, they at least named the first batch of the Z0 "prototype". It was basically a 2011 version R41, slightly shorter cap that covers less of the blade, which makes the shave a fair bit more aggressive. The later Z0 was more like the current R41 versions after 2013. Not sure if they made another minimal design update in between.
Their best head so far was the S9, a GC .84P copy. Then I also got a dual comb, X0 or X1 or X2, which was so much on the mild side that I quickly retired it as dud. People in general seemed to love it, but what isn't rated at 5 of 5 stars these days, cough.
For the "AX":
"Notes:
First Version The cap clamping blade is a little tight, thanks for your understand."
Not really, you should bolden that line like I just did. And actually maybe stop selling these heads...
They added it only after the complaints came in!
Reminds me of Sofirn, a flashlight manufacturer. Their SP35 model is really good, but the first batch had a defective automatic temperature regulation, meaning the LED always goes FULL POWER and doesn't dial down when it runs too hot, which is necessary to prevent heat damage to the LED itself.
What did they do? They sold it as "ENTHUSIAST/FAN EDITION" without ATR. "Always best brightness!"
And a lot people bought it and loved it. Oh well! But one must say, flashlight enthusiasts might even be crazier than razor collectors.
Klinker mentioned Boti, they seem by now to regularly throw some fancy small number razors on Aliexpress.
I got the current offer, the "Boti Vortex", in polished version and its handle is super grippy, despite polish. Seems to be hand polished rather than electropolish.
This is now going off topic, but I couldn't figure out which razor head they cloned. It reminds me of a cross of the Timeless Bronze head with a Game Changer. Yet rounded blade posts, which neither head has. Couldn't figure out which geometry they picked as template.
Quality is fine, the razor head is on the very aggressive side, both sides of the dual comb have significant exposure. Which reminds me of the Shield, which had the most exposure of all WR2 clones I had so far. I haven't got the AX and if I should get it one day, I would rather wait for the next batch/version. DSCosmetic will relentlessly sell them till they are all gone, so as the 1.55 316L steel version is sold out currently, that one might be a relatively safe bet to maybe of the revised edition. The other versions seem still in stock.
