It's completely a great rubber,, the speed is amazing, and the spin is great.. I used it on my Persson Power Carbon..

nice rubber, it gets dirty with dust very fast, have to clean it after each 30 min of game. good for begginers, not so fast but ok, need good hant to get extra spin. nice sound, per all i give 8 from 10.keep away from table edges.

Donic Coppa JO Silver continues to amaze me, usually when paired to high standard Donic blades (I'm not saying its not good for other branded blades). The rubber is okay, not that bad, not that hard. There isn't anything much to worry about its main spin because I find it fun to generate some spinny services. I agree at some point that it is an ideal rubber for beginners, but it is nothing compared to the Gold version. Looping is fantastic here, but not so fun for controlling its throw angle. Don't worry, its still a good rubber, but a little too overpriced.

A good, professional table tennis rubber but I want something harder with same speed but more spin... I have been using it for approx 2 years but now i think I am going to get the acuda s 2... the coppa joe silver are good rubbers but lacks spin

Donic coppa JO sliver is good for blocking, spinning and controlled style of play. but of attacking its far to slow
