This rubber is promoted ad an alternative to the Tenergy series. Well, it's not like Tenergy, its a tensor, but it performs very well.
I find this rubber very fast, its very springy, has a great catapult efect so it's better to have some skills to control this rubber. The sponge is a little fragile, so you have to be carefull when you take out this rubber if you want to use it again, its very porous too. The hardness its nice, the M3 its too soft for me, the M2 sponge its just a little softer than JP2.
The topsheet is very grippy, also fragile, it has kinda mate finish and it looks worn out soon, but it takes more time until its really worn out. The other thing about the topsheet that called my atention is that when i glued it i saw it had like little bubbles inside (just noticeable when looking in detail), i thought i made something wrong when gluing but then i saw others with the same thing (glued by people who has experience), however it doesn't affect the play at all.
It can generate lots of spin and good speed.
The worst part are the serves, due to the springiness its harder to make dead serves, but its still ok.
IMO this is one of the best rubbers outhere for its price.
