Pen Cap For Novo Nordisk FlexPen - 1 each

Works very well to remind me when was my last insulin. Concerned about battery life as the battery is not replaceableNew entry June 6. Product quit working this week. Very disappointed with the short battery life. Wasted my money.

Maybe i don't have to use this pen but when it works it is very helpful. Problem is their quality assurance is either nonexistent or a professional embarrassment. failure after failure after intermittent operation.All it is is a timer. a timer that is beyond these moron's ability to produce reliably.Wish i had an alternative to buying 2 at a time.Let me be clear- I hate this product w/ a passion

Great idea, terribly done. Battery doesn't last and can't be replaced. Someone smart needs to make one with a better and replaceable battery: they would, then, sell a lot of these. Rather than (greedily) offering the public an overpriced, inferior produce that needs constant replacing.

The pen did not work when I received it. The plastic strip protecting the battery was missing so the battery was dead. Since you cannot replace the battery I had to return the item.

The cap works great but the suppler sent me an out of date cap. Tamesulin stood behind there product and replaced it with NO hassle.

This pen top works well and helps to avoid mistakes. (When using multiple insulins or when distracted.) A handy tool, I am very happy with it.

When I learned about this I thought it was a great idea, and came here looking for it.Thirty bucks? Are you kidding? For ten bucks (which would give them a profit of several hundred percent) I would have bought a couple, but this price is ridiculous.And from the other reviews I see that the battery is not replaceable (seriously?) and doesn't last very long.No thanks.

This is one of the best ideas! A must have for any diabetic taking insulin. This system ensures you don't take your insulin too close together and always lets you know the last time you took it.
