I have been using this product for about 4 months. I had my eyes on the Mackie digital controllers, but the price of those was prohibitive. I soon discovered that audio on the cheap company Behringer had a product in the same vein. I have been quite happy with this since getting it. It is very easy to install, simply connect with MIDI, set your program to recognize it, and it works very well. The manual is unfortunately not that detailed, but you can find help online if you need it. You can connect more than one of these if you want more channels. It gives you 8 faders that are motorized, and with most programs you can write the fader automation on to your song. Then when it plays back, the faders will automatically move. You can switch which tracks are controlled by which faders as well, so you are not limited in that way. There is also a pan pot for every fader, so you can assign that to control panning or other things in your DAW as well. There is a limited amount of visual feedback in terms of display on this controller, but that is part of what you lose with the hugely lower cost of this when compared to the Mackie or Tascam controllers. In terms of sensitivity, it has worked totally fine. The feel of the faders feels no different from the Mackie one, which a friend has. There are also other handy functions. You can mute and solo the tracks that are selected for the faders. You can start and stop playback with it as well. One thing I don't like is that since it's cheaper components, it's a bit less durable. One of the caps on my faders has already come loose, and while some superglue fixed it that should tell you something about the craftsmanship. For the price, you absolutely can't get a product like this cheaper, so it's a great value. I am overall happy with it, so I would get it again.
