This pencil is nicely finished and comfortable to use. It is well-balanced too, with sufficient weight to give a good 'feel', but not so heavy that it is cumbersome and tiring.
However, it is for me far less attractive in reality than it appears online. I definitely prefer the Graphgear pencils (for eg Pentel 0.5mm Graphgear 1000 Mechanical Pencil Lead with Quality Brushed Steel Barrel Rubber Grip and Sliding Sleeve
): these are just as nice to use as far as balance and weight are concerned (only 2 grams lighter). Though less 'sparkly', having a completely matt finish, they are MUCH cheaper (particularly via Amazon marketplace where one can buy 2 Graphgear for the cost of one marketplace Rotring), are nicely colour-coded for different lead thicknesses, and have the significant advantage, in my opinion of having an easily retractable lead tube. (Just a click of the pocket clip does the job while the Rotring requires the tube to be manually pushed back as the cap is pushed down. It DOES have a cushioned writing tip, but I have noticed little advantage in this.) For me, the only weakness of the Graphgear is that the moveable sleeve which indicates the hardness of the lead in the pencil often is too loose to properly register: but then the Rotring has no potential whatsoever to indicate lead hardness.
I'm sure Rotring enthusiasts will not be disappointed. But for those who simply want a good, reliable, easy to use and attractive pencil which is available in 4 different lead sizes and is relatively inexpensive, buying one of the Graphgear options seems to me to be a no-brainer.
