Used for 3 years.

Interface first bought when I started on Ableton Live.

+: Ease of use, ergonomics, durability

-: Navigating between different modes, although it gives a lot of opportunities, demand a way to juggle live impractical and imprecise (volume, balance, effect sends limited to 8 levels)

good quality / price ratio

In the same situation I remake the same choice. Today, with other demands on my needs live, I'd rather to a more complete interface in terms of direct controls.
