Tested the rubber with custom 0.5mm sponge on the BH of a Globe 583 blade. Pips are horizontally aligned and rock hard, dose not bend at all. The grip on the rubber is just enough for lifting/roll-looping back spin ball and bringing the ball over the net when driving against top spin ball, almost no spin on serving. But the trajectory of the ball is flat and sinking when flat hitting/driving, the faster the stroke, the more it sinks, just like some "raw" pips out rubber but indeed it is a "cooked" one. Not recommended for pips beginners but can be a good option for pips hitter.

Great Pip out Rubber, not deceptive but fast, chopping and flat hit is easy to control. I changed playstyle to more offensive and can't get a consistent looping out of it. if i'm playing Classic Defense I'd happy with this.

Durability is minimal.
After a 2 hour session with the rubber, the topsheet started tearing away from the sponge. Not worth at all despite its low price per sheet

i tried a 889-2 with japan sponge...the surface very hard and the sponge very soft.very good for blocking and hiting but not good for topspin because with the hard pimples it is difficult to create spin and allso not good for chop any serve but good for push the serves
