I bought one in 2015. I wasn’t sure as it was old tech and I already had an old Novation Remote SL which i used for transport and quick controls but I have to say it’s great and I’m so glad I bought one. It’s got a great feel and it’s perfect for Cubase. Automating levels is a doddle with it. I love all the Cubase integrations like the e button to bring up the track window and more importantly the keyboard button that brings up the vst instrument window for a track. It’s so much quicker than fiddling around with a mouse.The AI knob may only be one control is great for automating stuff or even just fine-tuning; you just put the mouse over the knob you want to change and then fiddle until you’re happy. 
I find it easier to use it for the EQ section too as you spend more time listening and less concentration on clicking and dragging. All in all i’d say that it makes my workflow far simpler and less fiddly.
