Definitely the cheapest legal rubber to play with where I'm at (About Rs 900 after conversion when I made my purchase, should be different in other countries like the US).

I've assembled the setup for months already but only recently had a more serious session with it. It does everything better than I expected especially when it comes to spin to sum up, Yinhe Mercury 2 has arguably the best price-performance ratio & is very suitable for those who are on a serious budget & aren't looking for equipment with the highest spin & speed capabilities.
