Nice DSP with a lot of features

It's very compact and easy to install. The app is difficult to find without the QR code in the manual so don't lose the manual.
The app itself, at first is difficult to understand. There are no instructions on how to actually use it in the manual. Within about 5 minutes of changing settings and making adjustments I finally started to get the hang of it, and the user interface is simple enough to navigate. It connects through Bluetooth quickly and easily, and maintains a good connection.

One big issue I've had with mine right away is a clicking noise in channels 7 and 8, it starts out slow and gets faster and louder. If I go into the gain settings and disable those channels for about 5 minutes and reenable them, the clicking goes away and it plays fine. This only happens every few power cycles so I haven't really justified returning it.

Overall, I like this DSP. It's very useful, has all the features I needed, and has plenty of channels.
