    I have one of these. Was it issued primarily for domestic use? If so, I can’t imagine that many people figured out how to use it! It certainly leaves me confused. Gonna hang onto it though….the Trump presidency is barely 2 months old, plenty of time yet for him to do something that might make it helpful to own a dosage calculator…..;-(
