I haven't been keeping up; does TWSBI still have quality problems with their plastic? The last I heard, there were a lot of reports of parts breaking. TWSBI was always good about replacing the parts, but I heard too many stories about someone's second or third replacement cap breaking.
I haven't had any trouble with TWSBI's bought in the last 2-3 years. Besides they have a crazy good lifetime warranty. I've had a pen stepped on, emailed them and told them so and they shipped a replacement barrel to me for shipping cost. Ditto a replacement wrench that I lost.
