I have one. Purchased around the first of the year. I like it a lot. The 50 RPM to 5000 RPM infinitely variable speed is great with the turn of the dial. Digital depth readout in digital or fractions. I use the hole depth auto stop, the speed control, the various drilling modes for speed based on bit size (forstner, metal, etc). I have not tried the auto tapping mode but will.
There have been two software updates since I purchased. You plug a Windows machine into the unit and download their update utility. It will also update the SW with a Mac IF you are running a windows emulator on it, which is what I do.
The standard chuck doesn't quite go down small enough for a 1/16" bit, so I changed out the chuck with one from Amazon. But I've found runout to be minimal and the tool to be great to use. It is keyless and I replaced it with a Chinese import keyless that is accurate.
Yes the keyless auto hold is a cool feature too. For larger bits I use it but have found sizes below 3/8 in wood work with a hand tightening of the chuck.
Fit and finish are great. It does take two people to assemble and get the motor on the column. I upgraded from a 20 year old Delta and the difference is night and day in performance, torque, accuracy, etc. I made a custom top for it using Woodpecker's components for a fence, T-tracks, etc.
