NewNew Store sold me friendship focus 3 which was very old, and the foil from rubber damage the topsheet
First time I also got a red and a black sheet from different batches, and inconsistencies were apparent. Next time I also bought 2 pairs of 44 deg Friendship Focus III Snipe from the NewNew Store, and it was all from a newer batch with much better consistency.
Recently I had a deeper dive in table tennis equipment sellers of AliExpress. My experiences were somewhat variable, but generally there are at least 10+ mostly reliable seller. Sometimes communication is not their strongest point, but I didn't have any major disappointments, that I could attribute to the sellers themselves.
Manufacturers are another question, though. I fell for the marketing blurb of Sanwei and I tried their 'Taiji Light' rubber - and it was everything, just not light. Have you seen a Sanwei shaped rubber (~164×162mm sheet with an arced narrowing upper part), which weighed 73+ grams (black side)? Based on that shape, it would be at least 58 (maybe even 61) grams, when cut to normal size blade. And then, the red side was about 10 grams lighter, still definitely not light. So, for me, Taiji fits into the 'hell no' category, while I also had Sanwei Target 90 sheets with also different weights black vs. red, but at least, it was advertised with 39 degree 2.15mm thick sponge, so 64 gram on average (61.5g red, 66g black) seems sensible for them.
