i only played with this rubber for 2 sessions. but the fact that it's low-through and light impresses me. it's like a cheaper version of cj8000. the sponge is not as soft/bouncy as the cj8000, but the topsheet is grippy enough (non-tacky) that it generates enough spin. it's ideal for training and as save you tons of money. it's the cheapest, good-quality rubber i've ever used. the over-rated H3 is on my blacklist right now because i'm staying with less tacky rubbers. with this rubber, i don't have to worry that it would lose stickiness like the h3. the low through angle really requires a lot of body motion but that's very good for training. the rubber is slow, though so it's not ideal for tournament play unless you r a great player (someone who can beat the crap out of anybody without relying on equipments). killing shot is hard to make and it's not magical. but the price tag is really low - much lower than the suggested price here (10/piece) if u have someone to get it for u in china. i got my pair of amigo (1 black and 1 red) for like $5 USD/pair - it's insanely cheap!!! next time when my parents go back to china for vacation, i would have them buy a few dozens to resell here in the US - make some money!!!
