I use it for about 2 years and the sound is really stunning.
I tried the whole SERIES Roland and other brands such as Yamaha and Clavia.
I buy the TD20 prfr because it has an exceptional acoustic drum sound that allows me to play drums in an apartment without interfering with the neighbors.
I would do of course this choice.
In addition, many rglages sounds can be purchased on site to have real acoustic drum kits in a quasi tural noise.
