I agree completely with Greggy's comments. I started using this rubber in May 2009 after trying a bunch of other pips, and also tried a few others since I started using it, but, like him, I came back to it, because nothing matches it in terms of how dangerous it is for opponents. But he's also right: you need to really stick with it; it's not for beginners, and if your plan is to use pips to stand close to the table and block passively, this is definitely not the rubber for you. It's fast, and the pips themselves are soft and grippy, but for creating tons of spin variation for chopping off the table, mixed with occasional active blocks, it's amazing, and the backspin it's capable of generating off loops is incredible. Just know what you're going to be in for if you try this rubber: if you're the kind of player who wants instant results or expects new equipment to work wonders immediately, stay away! You need to train for a long time to get the hang of this thing, but it's well worth it.
