Cap it, Snap It and Go!
I'm new to insulin this year Doc told me NOT to take my basal insulin if I wasn't sure whether I took it or not.  After having a couple of episodes of over 300 blood glucose followed by blurry vision,  I looked for a solution and found this pen cap. Easy, easy, easy.  Snaps right on the pen and the timer starts.  Works perfect every time.  My only objection had been that you have to buy a new one about once a year because the battery is not replaceable.  However, reading at the site, one of the reasons why they chose this was for safety.  The cap will gradually wear and could potentially fall off over time. Inside of the cap can get dirty, which presents a hygiene problem. The cost really is nothing compared to the cost of insulin or the complications you can get if you can't remember whether or not you took your insulin.  My experience using this product was for basal insulin.
