I used a Novolog flexpen for many years and had no complaints.
Recently switched to Humalog due to change in insurance.
Whenever I'm injecting insulin, I have to push really hard in order to inject the last one unit. If I don't push hard enough, the dial goes to halfway between the 0 and 1 markers, but then pops back to 1. (and I'm not sure if the insulin has been injected or not).
Is my pen faulty or does anyone else experience the same problem?
