McC was sort of right about my point but I was really saying/asking, that in order to have two doses with you, you'd still be carrying six injectors. Only now, they'd be smaller and square. That may or may not save space. However, in reply to my post about the space issue twinturbo said she'd carry fewer, and that's when I wondered what she would do if this item misfired and she needed a second dose.
DD carries two doses with her and it's easier because she's a girl; though she was the only 10 year old carry a purse and is probably one of the few in 6th grade who does. The nurse also has two doses. I don't mix the lots in what DD carries with what the nurse has because of different expiry dates and insurance issues. Our insurance only allows up to purchase one twinpack per month and school requires that the expiry date on the EpiPens provided go past the end of the school year. So during summer camp and until it expires in the fall, DD carries the pens from the previous school year (as do I); that's how we stagger our purchases.
DD was very intrigued by the Auvi-Q and wants to get one. However, I'll have to see how insurance handles it. If it has a high copay for only one vs. our current copay for a twin pack, then we'll likely stick with the EpiPen. I'd also have to see what school prefers. It's likely, they'll want EpiPens.
