I've been using the rOtring 800 for five years now after getting it off massdrop in 2013. I have to say I was pretty impressed by both the pencil and massdrop. I tended to prefer my mechanical pencils, but had only ever had the cheap plastic ones. With about a couple months left on the pencil's warranty the lead holder started to fail. Massdrop totally came through for me though by not only refunding me, but also silently sending me a replacement pencil a few weeks later. I still carry it with me every day since.
