After intense consideration between the available e-drums out there, I have finally ended buying this set. I'm not a drummer, just a dad who wants to start learning and to give my son a proper kit so he can learn even more.
What is important to me is: how silent the e-drum is? I lived in an apartment, in Germany, where the neighbors are friendly as long as you are quiet. This kit is quiet enough. Imagine you hit your bed with your hand, that's how the sound it is. You need to understand that the low frequency wave travel further and this actually will never come from your drum set but from the foot pedal. Roland has a solution for that, you might want to consider.
The setup is quite tedious, will take roughly 90 minutes. Everything is intuitive on the control box. You don't need to read the manual too much just to get it running. The sound is almost realistic and the naturality of each step from soft to hard hit, is a bit harsh in my opinion. But at least my son, who knows how to drum, really liked it.
The build quality is superb. Everything is perfect fit with high quality material. Even the plastic part is durable. The cabling is a bit headache to make it tidy, but you can always use the given cable clam or use the market available ones.
Conclusion: if you have enough budget and thinking about investment where you will use the instrument for a long time and still have a good after sales in the next 5 years, this might be a good choice.
