I wish I could get a Clickstar or any other pen for use with Insulin Glargine that registers more than 40 units. At present I've been given an Autopen 24 that only goes to 40. So I now have to inject twice as I need 52 units.
I used an Autopen a few years ago and found it a bit unreliable - and with use the scale of units rubbed off.
I like that my Lantus is not in a disposable pen, as my Novorapid is disposable and I hate that I have to throw the pen away.
