New Dead Rubbers, Moon, Rapid Speed

Ok, so I was trying to find an equivalent to Hammond Pro Beta and ordered two Chinese rubbers off AliExpress from New, New Sport. An equipment experiment. Both arrived quickly and undamaged in sealed packages, by air freight. Glued the Yinhe Moon (max) on my Ludeack with Tear Mender, rolled and let stand overnight pressed under some heavy books; the Moon played with less bounce and grip than my 20 yo Yasaka Tornado 2.0 (black). I read one reviewer's comment on Moon that it took some playing time, but this was no improvement, so I tossed it. I used the same process/same glue w Rozena (on the Ludeack) and it feels, and plays, fine.Then tried a black sheet of the KTL Rapid speed (2.0) on my Darker Aqua blade using the same process. The Rapid felt ok with a bounce test before cutting when covered with the clear, shipping plastic sheet cover, but when I cut the rubber and removed the plastic factory cover, it too felt very, very dead, with hardly any bounce. It is grippy.  I don't see or feel air pockets. It is unplayable and will likely be tossed.

Simply put, they don't exist. They will never feel any better, I learnt it the hard way too. 

Thanks John and Cole_ely
