Really horrible. Doesn't work most of the time. It crashes more than 75% of the time at launch. I can keep re-opening, or ignore, the launch again, but the bottom line is that it doesn't work most of the time. I switched back to Transmission. It's not as pretty, but it's completely stable.
If they ever fix this one, I will try it again. I do like the looks of the interface more, it's just completely unusable. It didn't work back in April when I tried it before, but now we are many versions later, and it's still not fixed. MU says 3.2.3, and I tried it, but then I even tried 3.2.4. MU us just one version behind. None of them work.
