Nice budget electronic drums and upgraded version of the Nitro series, I had the older model and the differences are that this one has a much better head with more realistic sounds, songs, exercises, Bluetooth connection to play along with your favorite songs or do online exercises, and a stand for a mobile phone or tablet. The snare is bigger than the old one and the other pads don't have that basket that the drumstick used to hit, and they are open at the bottom so they don't collect dust. The negatives are that it doesn't have a mesh bass drum (I have added a Millennium from Thomann), the frame is thin and lightweight, especially for the snare they should have used a larger tube, but if you screw it and tighten it well and stabilize it with clamps, it's fine. Finally, you can connect them to a computer/laptop via USB and have a real drum sound recorded by professionals in the best studios in the world with EZDrummer. There has been an upgrade in this area as well, as when you write MIDI, it accurately reflects the sensitivity you have set on the head. I have made detailed unboxing, setup, and demo videos on YouTube for anyone interested
