I have been using more or less 3 years. It serves me as a volume knob between the outputs of the interface and the active monitors.

For the price, it plays its role. This allows a correct level output interface before attacking monitoring.

I am satisfied. This is not a war machine, in the sense that it is a little fragile to me. The button is very big it said ... but it must go smoothly into use.

It lets you toggle on various monitoring systems, also with a grafted with preamps + headphone (which I think is very bad ... but it may help to return additional headphone)

I will change afterwards with a SPL, but the budget is not the same. The equivalent SPL is much more pro.
