I have one.
It's well built, high quality, nice and compact and comes with a great case.
What it doesn't do well, is stropping or sharpening with a very light touch.
You need a specific amount of force to make it "seat" into the set angle while you're sharpening. Basically - as you push down on the stone holder when sharpening, it raises the rear rod to make the angle align with what you've selected. This amount of force it far too much for stropping or for very light and precise burr minimization.
I also would like to have the option of alternative clamps, but it only comes with the one "double" whole milled clamp.
For general and quick sharpening, it does a good job.
