For how long have you been using it?
I use it for a week

What thing do you like most/least about it?
Great, the pads are perfect, easy to use and installation, the manual is complete, the pad X / Y is an advantage over some other products.
What I like least, unfortunate that there are only two assignable knobs ...

Did you try many other models before getting this one?
No no, he convinced me by his price, and various opinions I could gather on the net.

What is your opinion about the value for the price?
Excellent, bought € 155 on Woodbrass is a control surface I think the cheapest
