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!!

was so impressed how quick it came. Love the product, battery died after 1 year or so and cannot be replaced. This is one great invention for us diabetics. It records the last time you took a shot. which is so valuable in this fast paced world.works great. i have a similar top for my humalog pen to. battery still going. Thank you!! Lifesaver

It didn't work. I opened it to know why, even when I knew that after that the product can't be used again. The battery was rusty. The product is excellent (when works) and the price is awesome but if battery comes used then it's useless.

Very helpful to use but doesn't stay on the best

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.

Great idea, great product. I want one for pills that shows how many times it has been opened each day and when.

This is literally a life-saver! I read about the Timesulin product about a year ago in Diabetes Self Management Magazine. I was so excited when they came out. I absolutely love this product! It lets me know how long it has been since my last dose of insulin. No more guessing!!! I have recently changed my long acting insulin, so had to purchase the appropriate pen top.Make sure you match your pen type to the Timesulin Cap type.HIGHLY RECOMMEND!
