Mine was pretty tough to get off the first time as well, but didn’t need tools. As far as the software goes, it’s very intuitive. Just remember when you get everything set up you have to click the “upload to device” button on the left. I somehow missed that part and had an hour drive home in silence after installing it.
It’s VERY nice to be able to set everything up beforehand (like crossovers & speaker distances) and then quickly upload the tune. Especially since all I needed to do was transfer settings from my previous DSP.
