The pro-1 isn't the easiest analog synth for a beginner, and has a few quirks that could throw off even an experienced synth user. However, getting past the eccentricities there isn't much to wish for in this synth.
Great sound, lots of direct control, great build quality, good price and did I mention it sounds great?
The only downside to this product is that any firmware update requires it to be connected to Behringers Synth Tools app. I understand that this app has several features not accessible by other means, such as midi-clock internal/external, and I would have liked to see some way to change these settings that doesn't require me to download an app.
For the price you cant beat it.
