iLet App 4+

ILet is an incredible device…..

The ILet pump and its app are both incredible and easy to use. I have personally lived with T1D since 1982 and have been using various pumps since August 2000 (Disetronic, Animas, Medtronic, Omnipod, Tandem and now ILet).
This pump is what I have been dreaming about and hoping to have for years.
It is accurate and so easy to use and benefit from.
I am looking forward to the future with new options with Beta Bionics and ILet.
Anyone that wants accuracy and ease of use and not having to think about diabetes all day long, so get with Beta Bionics and ILet.

Not ready for prime time.

The iLet decides when to give insulin based upon your meal announcements and what it has learned about your habits. In theory, you never have to count carbs or worry about how much insulin to give.

The corollary is that you can’t make any decisions. You can’t decide you need more, or less, insulin. There is no way to make this machine work as a standard insulin pump.

After following the instructions, I found the iLet simply wasn’t doing the job. There were many nights when my blood sugar sat above 300 for hours. But you can’t argue with the iLet - if it “thinks” you have enough insulin, you’re expected to simply wait until your body agrees.

Betabionics doesn’t have a backup plan for what to do if this machine doesn’t work for you. At first they told me to wait and be patient while my glucose levels were dangerously high. Allow the iLet to learn. I’ve had Type-1 diabetes for more than 40 years, and have never been under such poor control as with the iLet.

If pressed enough they’ll advise that you unhook the pump for a while and use syringes or to change your infusion set. But ultimately if the iLet doesn’t work for you, you’re out of luck.

I wanted the iLet to work. I like the concept. But it’s just not ready. It now sits in my desk drawer, unusable. For anyone considering purchasing an iLet, consider a Tandem or Medtronic or Omnipod instead - something with a track record.

Developer Response ,

Hello,
The iLet is designed to learn each individual user and makes 100% of the dosing decisions so the user doesn’t have to. When following training guidelines, the iLet algorithms will learn to react over time to the user’s highs and lows, based on meal announcements and glucose levels. Because the iLet works so differently from other systems, training from a certified iLet trainer is important so that the user know how best to help the iLet learn their insulin needs. Please give us a call at 1-855-745-3800 and we can help with questions or troubleshooting with the iLet.

Not sure about some of the bad experiences I’m reading about on here…

My a1c has been low to mid 6’s since I can remember. I’ve always just been on shots. I never wanted to use a pump bc of all the hassle and my numbers were always good. I tried iLet bc I was frustrated with my “rage bolusing” and I was always fighting lows after fighting highs.

The ilet hasn’t changed my A1c’s (6.0-6.6 since starting in sept 2023), but it’s allowed me to “let go” a little and not worry constantly about my glucose levels.

Again, this is the only pump I’ve ever wanted to try bc it looked so easy to use with not a lot of work. And I’m really glad I took the leap!

The new app is way better than the old one. I can look at my phone to see if/when I announced and what my level is. Nice features.
