I've been playing with this rubber for almost a year and it is still nowhere near being used up... It might have lost a tiny bit of speed or spin, but heck. Most of the rubbers I've used were very used up after 6 months. This is one of the two rubbers that withstood the hardest test... The test of time.I don't think there is much point in describing this rubber characteristics because it has been done to death. It smashes rather well, it does top spin well, it blocks well... Very good all-round and it just won't die. If you are short on money. That is the rubber to get. By the this time I would have killed 4-5 sheets of Jupiter 2, but this still is alive.
