I use it for 6 months. And it's been 6 months that I played drums. I have not tried other models, I relied on feedback from users who are confirmed.
Personal I am sooooo happy. I just play like crazy and I love trying lots of different kits. I love metal but I like playing with kits drum & bass and other "one man band". Finally it is the kits more "electro" plug me the most. Side drum sound, the kit "groove" that I use mainly. I love the sound of the snare on this kit, if I buy an acoustic I will try to find the DC that gives this sound.
In terms of navigation between the kits, I think some have not read the manual
To scroll through the kits to speed "normal" (so slow as pointed out the person who gave his opinion below) he was press "+" or "-" that it had been understood.
To scroll faster you have to press "+" then "-" (together) or vice versa. This has the effect of speeding up the scrolling.
To go faster still must be pressed in addition to "shift". And then there are ways to spend a kit to 99 in 2 seconds.
This procedure also applies to vary the tempo or scroll through the songs.
