Its got a smooth rotation, but the metal itself seems unfinished, plus it doesn't have any heft to it making it feel cheap.
To top this off, the setup was awful. To start it didn't even recognise it as a USB device, then after 30 mins of fiddling it finally registered but was unable to read the USB descriptor. A few reboots, drivers, windows updates, trying every USB port it finally works.
For a volume knob, I have to do about 4 rotations to go from 0 - 100. This to me is ridiculous.
BMWRiderGlad someone read my comment! Enjoy it. For everyone else, the surface dial can be bought super cheap on ebay/facebook marketplace etc. You really cant beat it for quality/price.
