Much as expected with very good performance.
I have been looking for a means of sharpening JP type blades for a while.
However, one serious problem lies with the thumbscrew mechanism to tighten the blade to the guide. The rotational movement of the pressure pad which theoretically allows for independent movement of the pad from the tightening screw never the less imparts a degree of rotation to the blade which has been fitted to the guide. As the guide does not have a means of fixing the blade at 90 degrees once the blade is fitted, it tends to drift from 90 degrees as the sharpening commences, or even before sharpening has started.
An obvious improvement would be to replace the screw pad with a cam lock mechanism to ensure the alignment of the blade; such that once the blade is fitted to the sharpener, the alignment is maintained and not distorted when the screw is tightened. This is particularly evident when sharpening narrow chisels.
Another improvement would be some means of ensuring the blade is set at 90 degrees to the jigs alignment. This would obviously need to allow for variations in the fitted blades width.
Otherwise an excellent device.
