I've just bought the UAC-2, principally as my laptop is USB 3.0 on all ports. The driver is a Win 8, but works in Win 10. The unit provides excellent sonic performance despite not being overly versatile on the ports front, and to me, Sonar isn't showing the actual latency I believe I'm getting. I tried the similarly specced Audient ID-14 and received nothing but trouble in Sonar/Win 10. Loads of dropouts, clicks, pops etc. and couldn't find a single ASIO setting that worked, yet this unit has yet to fall over, click or pop. I really like it.
