9 purchased and 6 committed, which means it's 5 people away from another $2 price drop. Even with current price, it is not a bad choice if you are looking for the black 0.5 mm build, which is over $80 on Amazon or Jetpens. Other builds are slightly over $60 on Amazon.
Rotring 800+ is an upgrade of 800 version, which is a solid drafting mechanical pencil. Since the sleeve and lead are fully retracted, it makes 800 series a good pocket pencil.
"The Rotring 800+ Mechanical Pencil + Stylus Hybrid conveniently combines a mechanical pencil and stylus at the same end! With its unique retractable mechanism, switch seamlessly between the two by simply twisting the top to extend the pencil or retract it back to use the stylus. The capacitive stylus works on smartphones, tablets, and other touch screen devices. 100% effective at every angle, the precision stylus tip allows for high accuracy, control, and speed. The mechanical pencil features Rotring's brass mechanism to provide precise lead advancement, and a fixed lead guidance sleeve prevents breakage and offers a clear view of the page. A knurled non-slip grip provides comfort. The tool's ergonomic metal barrel has a nice, balanced weight, and its hexagonal shape ensures fatigue-free writing and drawing and keeps the tool from rolling when laid down." — JetPens
At check-out, you can select either Black or Silver finish with 0.5 mm or 0.7 mm lead size. Quantities of Silver/0.7 mm are limited to 17 units. (According to my experience, 0.5 mm is more popular than 0.7 mm and black is more popular than silver. Don't know why the least popular build in my opinion has limited quantity)
I've got the 600, love it. Has a nice weight to it and the quality seems very high. I'm sure the 800 is even better.
