For only around £12, it is a pretty smooth pen and is pleasant enough to write with. It has a nice weight to it, not too heavy and not too light so won't give you hand cramps after long writing sessions. It is, however, a very dry pen. You won't get much shading with this pen especially with the standard Parker Quink cartridges that come with it. The Parker inks themselves aren't exactly fantastic either - they get the job done well enough but are fairly bland. The blacks aren't very black and the blues look very washed out and don't stand out. I would also not recommend trying to convert this pen to an eyedropper pen, since the barrel is made entirely out of steel and ink will rot the inside of the barrel.
The nib is a nice medium, suitable for those who have both small and large handwriting. You will not get much flex with this nib - if any at all. Press too hard and you will bend the tines of your nib and be forced to re-align then with some tweezers or a spanner - so don't try. I learned this the hard way but managed to fix it.
The nib and feed are easily removable by holding the nib and feed in a cloth or something soft while gently twisting and pulling on the grip section which eventually comes off. The nib clicks onto the feed with little tabs on either side of the nib which keeps it in line with the feed. It can be easily taken away from the feed to clean and then snapped back into place. Very easy pen to clean.
It is definitely a good starter fountain pen though, a gentle introduction into the world of fountain pens and certainly pushes you towards buying a converter and trying out bottled ink. Very happy with this pen considering it was less than £15.
