This is the best value for money market ... Nothing to do with a Pearl Export example!
For a midrange, it sounds really fine, even recording (studio pro) is doing it (but hey its just 80% of the musician!).

The bass drum 22 'will really get a big sound with lots of sub.
Toms 12 'and 16' are adjusted in 2-stroke 3 movements and as usual the 13 'just fuck the shit!

In conclusion: build quality, robustness, its happening everywhere ... Ideal for turning on a budget ... Or start the drumkit with a real instrument!
