The medication does NOT dispense properly or at times at all!! We have CALLED and NOTHING has been resolved! This is a life or death issue!! I totally expect SOMEONE to at least acknowledge that there is an issue with this inhaler. We have purchased TWO and have had the same problem with both inhalers. These inhalers, as YOU know, are not cheap!! PLEASE FIX IT OR YOU WILL CAUSE SOMEONE TO LOSE THEIR LIFE!!!!!! User's recommendation: As you doctor for a different product. Don't risk your life with this.
