Good quality but there is a catch:

If the racks are not very deep and they are focusing on weight forward, we must be careful not to tip the rack to allow manual movement, what happened to me, otherwise it will fall steeply the beautiful facades of your favorite synths and effects. "Fortunately" for me, a volume knob made for everyone, "buffering".

So, I took another brand, Millennium, the SR-2012 for example, which provides the blow by inserting the rack 4 to 5 cm deep to avoid this.
Now it is perhaps a little deeper ...
