The clip holds so firmly I don't worry about it slipping off mid-dose, and the magnifier makes those tiny 1/2 cc lines actually readable. Makes drawing up insulin a lot less stressful.

I had been squinting at syringe marks for years, but this little clip-on magnifier makes the 1 cc lines crystal clear without any glare. The firm grip on the barrel is a nice touch too.

My eyes aren't what they used to be, so those tiny tick marks on a 1 cc barrel were getting rough. This thing clips on tight and suddenly the half-cc lines are actually readable.
