Anyone had experience with these? I'm not using them anytime soon but eventually I will since they last till 2016, but my buddy is switching to a longer lasting slin and asked if I was interested so naturally I said yes and grabbed these off him.... Only question I have is since it's a 3ml/100 unit/ml pen is I noticed that it only has 60 marks on all 7 pens so if I had to guess then every 20 is a 100units ? Correct me if I'm wrong
