All I can say is that I wish you could get one for Lantus cartridges! The difference in design quality, and build quality is HUGE between the Autopen 24 and Novopen 3… I don’t think I’ve ever been annoyed by the Novopen, it’s just done it’s job, right down to saving insulin when I screw up and over a click (I hate that waste spurt when you over do the does on the Autopen – I’ve watched 30-odd units vanish into the air before after forgetting it’s a two unit click…)
Feels classy too, being all metallic and sexy…
