Lets see. I think for the price it is fine, but after having it for a while, I came to notice a couple of annoyances? which I will mention here, as there is enough reviews talking about the positives.
The hihat controler is not so good. I think it is decent when it works, but splashing the hihat is pretty much a guarantee. No matter how slowly I lift it, once it reaches the open value it splashes every time (at varying volumes), which is extremely annoying. I even set the velocity adjustment to the lowest value and it did not help in eliminating it. Why not use the tried and tested controller design I do not know, but I think the controller on MPS 850 felt better than this one. Hitting the half open sound can also be annoying, it seems to be quite a narrow window.
The snare pad misses hits. I dont know if it is playing too strong or a combination of head tuning along with strong hitting, but I notice the snare misses hits and produces no sound (mainly noticed this when practicing/performing flams, so take it as you will)
I will also mention, that the ride bell seems to be alternating bell and normal sound, even though the module still shows bell zone hit. So while the module can recognize you hit the bell twice, one sound will be bell and one regular ride sound. Have not tested with software, probably not a problem there.
The metronome is quite limited. I mean, I would expect at least basic quarter/eighth/sixteenth/32nd clicks present, these are the ones most used during regular practice. I would also expect triplet/sextuplet option. You can sort of fake it with 3/4 and 6/4 options but its not quite it. So if you prefer those clicks tough luck, only quarter note is really there. I also wish it would be easier to change metronome volume, you can only do it in the specific metronome menu, no quick and easy way to do it in the kit select screen. Maximum bpm setting is 240, if anyone is wondering.
