This is perfect for keeping up with your insulin dose times. I am very active and busy so the last thing on my mind is what time I took my last injection. This takes the guess work out of it. As soon as you replace the cap back on your pen the clock starts. I have been using the same single original cap on all of my pens (1 pen per week) for over 2 years without having to replace it. The battery just seems to last forever but I have a new one ready to take it's place when needed. The good part about having a back up cap is the battery is not activated until you remove the insert for the new cap prior to using it. I hope they keep making these because I depend on them to keep up with my dose times. They are great!!

I used to have, long ago a pen device that I placed cartridges loaded with insulin into. The device had a ratcheting plunger to set the dosage and this was indicated on an included LCD screen. This information would remain on the screen after injection for a little bit, then turn off. By pressing a button I could check the last injection easily. For whatever rea$on, they discontinued that and we have the modern insulin injection pen. The Timesulin is a 'Of Course!' solution that is totally and completely effective in ensuring you don't lost track of your injections. I only miss that the previous system also recorded the dose.

When is working this is a great product however exposure 2 moisture or dropping your pen, which often happens when you are out and about, causes it to work incorrectly often with the LCD screen only showing the hours or minutes. This made the pen cap useless, I've had to order three pen caps in the last year to replace such loses. I love the idea but please make it a little more robust

I've had a number of these insulin pens -- both my cat and I are diabetic and rely on them. They tend to die fairly regularly. When they do, I repurchase. This one lasted 2 days and Amazon says it's ineligible for return. I'm OK with some limited lifespan, but 2 days is not acceptable, hence the review. Disappointed!

This has saved me from double injecting (or not injecting at all) a couple of times. It just tracks the duration since you last pulled off the cap. It's smart enough to have a timer on it that allows you to pull the cap just to check your insulin. If you get the cap back on the insulin within 8 seconds, it won't register that you injected. I only have 2 complaints: 1.) Every one in a while, it won't register that I put the cap back on and it just blinks 00:00:00 at me, and 2.) It's got built-in obsolescence designed into it. There is no way to change the battery, so once it's dead, you are supposed to throw it out and buy another. I hate that approach to products - especially one your selling to people with an incurable disease. It just seems wrong. But I still like the product, and so far the batter has lasted for a long time (I think over a year now), so I'm happy with it.

Bought two of these; one for my son and one for my husband. The first one is working well (so far) but the second was fading in and out from the second I removed the battery protector. Now, 4 days later, it's just not working at all. I knew the battery wasn't replaceable do this wouldn't last forever but for this price I expected a device that lasted longer than a few days.

I think these should be given away free to first time insulin users. From what I understand this was designed by a diabetic and is very useful. It tells you when you last took a dose of insulin which has stopped me from taking a dose too early and showed me that I had waited far too long sometimes to take a dose. I HIGHLY recommend this to anyone who wants to keep better track of how long it has been since their last dose of insulin.

For those of us who occasionally forget if we took our insulin, this cap is perfect. Everytime you take it off to give yourself your shot of insulin, you click it back onto your pen and it starts at 0 and lets you know how long its been since your last shot. I no longer stress out about if I took my shot or not. Great price and lasts a year.
