Some well documented things that give pause about the manufacturer (check the comments section on the linked article or the Bad Gear episode on the Pro for a quick catch up if unfamiliar), but the sound of the Uno synth has always been good. Beyond that, UI and build quality on the previous versions made them non-starters to me. As long as the build has improved it looks like they've addressed the UI issues pretty well. Nice feature set, dual filters are always welcome, and the vids I've seen on this sound good as expected.

I'm sure if you're into what this synth seems to offer you will have a lot of fun with it. I'd personally go with something else if I was in the market for this kind of thing right now. Plenty of worthy contenders, though they'll have different assemblages of features than this does.
