I have two Sanwei blades via spinfactory.de official Sanwei reseller in Germany and two Sanwei 75 alc inner and outer via AliExpress.
I haven’t tried the inner but indeed the rest plays very well.
Just why aren’t any of the 75 serie on their website while they’re saying we don’t sell on Ali.
It's a feature of international corporations. Our helpful Sanwei representative is employed by Sanwei Sport which is likely their foreign (outside of China) operations and a completely different entity than whatever Sanwei's China operations are. This is a legal fiction, and ultimately it's the same people that own both.
However, they probably operate independently, which is why Sanwei Sport (the international facing company) can say the 75 series is not an official Sanwei product, as they are referring to Sanwei Sport and not Sanwei China.
Why separate the two companies like this? Probably because Sanwei China has situated itself as the low cost TT company in China. Whatever low price we're paying on Aliexpress, Sanwei blades and rubbers are even cheaper in China. Sanwei likely realized their cheap blades were competitive with the European/Korean/Chinese brands and that people from these countries were paying high prices for equivalent blades, so they decided to re-issue their line of blades with new model names and better finishing, and charging more than their China prices but less than companies like Stiga, Yasaka, etc.
For example, a 5 ply blade ALL+ from Sanwei China is probably around $10-15 in China. A Sanwei Echo which their international company sells is $25. It competes with blades like Yasaka Sweden Extra ($35) or Stiga Allround ($50).
