I am LIVID! Unable to get the user guide online, the BAYER website crashes trying to open the user guide. ALL calls to the customer service number many different times of the day are dropped on their end. My father is a brittle diabetic and hasn't been able to get a reading in THREE DAYS!! This is life threatening. He lives an hour and a half away and I can't get any help anywhere to explain the reading he gets which is a number 3 and a mark and another 3 (they could be m's but I haven't seen it).
