This is my first MIDI-controller, so keep that in mind when reading this review. I went with Arturia because of the great software you get with it. You can have hours upon hours of fun with the included sounds/software/plugins. The software sounds great and works very well with the MIDI-controller (which I guess makes sense since both are from Arturia).
The quality of the keys and pads feel like plastic crap, but I guess this is the case for any MIDI-controller/keyboard in this price range. For comparison I tried the similarly priced Akai (MPK Mini MK3 in red) and can say that they both feel like crap. I prefer the Arturia Keys and the Akai pads are marginally better (bit nicer feel/feedback) imo. But as I said: a plastic feel is probably to be expected from products in this price range, so I won't be too critical of it.
All in all I'm happy with this purchase and I feel I made the right choice for my first step in to keys/MIDI.
