I have used the device bought even cheaper and now set it up in a few minutes. The beta 3.0 version of the driver loaded for Mac OSX down overflown PDF manual, at first was not all set the same, but the driver works great and is working with the Logic key commands together. Considering the possibilities for such a complex program like Logic wants to use, you just need a few minutes to set everything but the one gets out again, if you have ever used a 5 button or Jogweel quickly back inside. So I'll never work (at home) without the part. It is more pleasant than to mouse or other devices (which I also have) to change. It's so easy to set up the thing that I do not understand why some complain here about the English manual. Google translator and a minimum logical thinking help because more (or a primary school child). The criticism, the keys should be stiff, I can (at least in my unit) does not confirm. This is certainly subjective, but I guess if the key would go easier, you would have to expect accidentally deploy. So for me the pressure point feels comfortable to the hand and is ergonomically favorable, than a mouse, but that is my subjective impression.
