How shockproof are Humalog and Novolog pens?

Every now and then, my novolog pen goes wonky and I receive the — for insulin injected. I don’t know if the battery is weak. I’ve come to rely on the memory feature, especially if I’m taking a few corrections.

How long have you been using it? The batteries are supposed to last five years. Although this is probably based on 3-4 shots a day, so if you’re doing a lot more, that’ll probably be shortened…
