For someone like me who's an occasional drummer and just wants the possibility to practice at home without annoying the neighbours, this is a great purchase. I'm sure a professional drummer would have plenty of things to reproach to this Roland HD1 but this is not a product targeted for them. So if your needs are the same as mine -just have fun without spending to much- don't hesitate and buy it.
Obviously when you buy the lowest form of a product, you know it's not going to be amazing, and it isn't. While it does the job excellently, the hihiat is massively low in volume, i guess the sensor is not as powerful as the rest of it. However, it is a great starter kit
