I'm not a very good violinist. So it's hard to say how much better this is than the $2 cake that came with my rental violin. In any case, when I got the Sartory, I gently wiped down my bow hair as best I could with a clean cloth. Trying to get rid of the old rosin on there. Then I rosined up with the new cake, being careful not to hit it with the frog of my bow. I've compared my $400 violin outfit side by side with more expensive violins ($1,000-$1,700)... I couldn't really hear or feel a difference. Switching to this rosin I did feel a difference. So that's pretty cool. It felt grippier, especially on the G string. It's very subtle and I very quickly became accustomed to it, so don't get you're hopes too high. You can't buy skill, nothing can replace practice. Which brings me to my favorite part of the rosin, it makes my practice ritual just a little bit more fun and satisfying. This rosin is such a pleasant way to start your practice, with something that just looks and feels premium from the wooden case and its magnetic fasteners to the flawless cake itself. That's why I bought it, and it filled that roll perfectly. A nice piece of equipment to make my hobby that much more enjoyable.
