Anyone used these before? I think Demon Tweeks sell them
  I've been given one (really useful quantity!), and am thinking about fitting it to the rear caliper, since that seems to need a regular bleed as it seems to get more bubbles than a deep sea diver. 
 the website's full of self adoration, but real world experiences are preferred to the websites quotes. If they're good I'll buy some...
