      Hey its not for me, like i said its for those too stupid or cheap to
      own one. I have 2- long (12") and short(8"), plus a hygrometer, and i
      recently purchased an ATC refractometer (oh its a nice piece of kit-
      and far more durable than fragile glass tubes too!! $60AUS including
      postage from ebay. Highly recommended. I also have a 500ml graduated

      Cant have too much measuring equipment i say. Dont get me started on
      temperature gear!!!
