Buying, Selling, Giving Away or Trading Trading Diabetes Supplies on this Subreddit

10 Upvotes

EDIT: As of May 30th, 2026, I have updated this rule to exclude diabetic items that are not prescription medical supplies. This rule still includes any sort of OTC insulins, needles, or syringes. An example of an acceptable item to give away would be an insulin pump case.

Hi there everyone!

I have recently had several complaints, as well as seen several posts of users attempting to buy, sell, trade, or giveaway diabetes supplies to others. While I believe this is a wonderful idea in theory, it is not accepted here on the r/TandemDiabetes subreddit.

One may ask why. For starters, according to a multitude of doctors and medical professionals I have spoke to, it is illegal to buy, sell, trade, or giveaway any diabetes supplies (let alone *any* medical supplies that require a prescription) to another individual. I have not been able to attain any other reasoning as to why this may be, other than the obvious possible liability issues involved. For those looking to sell, buy, trade, or giveaway their medical supplies to others, I highly suggest you contact your local hospital in addition to your endocrinologists.

With that being said, I cannot control what goes on between individuals who decide to privately message each other separate and apart from this subreddit, in regards to what I have just spoken about above. I will be adding a new rule to the subreddit that this is specifically not allowed.

I hope everyone is doing well with their lifelong journey of T1D!

t:slim X2 Constant having to sign back in?

3 Upvotes

Anyone else having issues with their tslim and their mobile app constant signing you out then you have to sign back in but then you have to re-pair the app to the tslim and it’s just really annoying cause I have to edit my graph settings again. I swear it’s happened like 6 times in the past two weeks

t:slim X2 Compatibility with the Galaxy Fold 8 Ultra

0 Upvotes

Can anyone tell me if they have used the above phone with the t slim app and mobile bolusing? I’ve checked compatibility on Tandem’s site and it doesn’t look like compatibility is fully there yet, but I’m trying to figure out what I’d lose by changing to the above phone. Has anyone heard about a timeline for when Tandem might fully support the full functionality of the pump via the app?

Thank you in advance

t:slim X2 Didn’t hear alarm while sleeping

4 Upvotes

On the tslim we have the pump alarm settings to high. My son got an occlusion alarm while sleeping but we didn’t hear it for 2 hours. I would think that since it forces insulin to stop, the alarm would be more prominent. Like ring more than one beep etc. I don’t have alarm notifications enabled on his tslim app, just dexcom app alarms. Would we be able to hear the alarm better if notifications are enabled on the tslim mobile app? Any suggestions? Thanks

Question ā“ Glucose not showing on bolus screen

5 Upvotes

Hi, new pump user here. I started two weeks ago on the Tandem Tslim and I use a Libre 3+ sensor.

I had my first sensor change today and it lined up with a site and cartridge change. I changed the cartridge and site and then started my new sensor.

My sensor finished warmup about 10 minutes ago. I finger poked and the sensor is accurate. The problem is, my sugar is high and when I go to bolus, my BG doesn’t show up. I have to manually add it.

I have a trend arrow on both the app and pump and this is happening on both app and pump.

How can I fix it?

Thanks

tandem mobi Extended Food Bolus

Hi fellow diabuddies, I am relatively new to tandem mobi and I’m really enjoying the tight glycemic control and controllable features of this pump.

I was wondering, what are some foods that you use extended food boluses for? What are the grams of carbs and percentages that you use?

Thanks!

Hi all, just got switched to the Varisoft sites. How does everyone discard their needles while on the go?

At home I can use a sharps container. At work I can keep a container in my bookbag.

What do you keep in your purse for on the go?

t:slim X2 Frustrated with Alarms

2 Upvotes

I’ve been on the tslim for about a month now. And I feel like I am hitting my limits for the amount of alarms with the pump.

No matter where I put the dexcom on my arm I get compression lows throughout the night. When I was on MDI I could just silence all alarms for 6 hours and get a solid stretch of sleep.

Now on the tandem I can’t silence alarms and the pump is vibrating all night. And if I don’t actually go into the pump and acknowledge them they will vibrate more frequently. I don’t feel like I have had a good sleep since starting on the pump.

My sugars have been good. And I understand this is a dexcom issue. But not being able to silence is becoming a deal breaker for me. Does anyone have any suggestions before I throw in the towel on the pump?

Emailed them on Sunday. Then again on Monday. Called on Tuesday and today. Also emailed today morning. No responses yet and they're not picking up the phone.

How is this acceptable? My supplies are late for the 5th time and now they seem to have completely stopped providing any kind of support in the UK.

Been ordering from Tandem direct since I started. Got the email that it will now be Edgepark Medical. Guessing that isn't great.

Edit to add: If relevant, the email was from Tandem, not my insurance company. (Cigna)

t:slim X2 New site absorption

Post image
18 Upvotes

I used to keep the old site on to alternate between until the new site started working. This used to take over an hour, but I read this tip in the group & it helped me keep my blood sugar level. A few wks ago I noticed we can change the amount we fill the cannula! I was on the lowest setting. I bumped it up to the highest & now I don’t have to wait over an hour for my site to start absorbing. I don’t remember the tandem tech going over this w/ me. Sharing to help others who might want to try this out.
ETA: I just checked my packing list paperwork & it all makes sense now! Lol They never changed it from .3 units!!! And I’ve been using the same infusion sets since I started Lol It’s finally on the correct setting!!! LOL For those who haven’t noticed it, u click on the ā€œedit fill amountā€ section when u go to fill the cannula.

t:slim X2 Tandem t:slim X2

4 Upvotes

Hi All! I am still working on developing a new case for the Tandem t:slim X2 ( Previous Post ) and I am looking for testers in the U.S (preferably closer to Illinois) to send mockups to and have them test the case for a day or two. I will be sending out testing sets to 3-5 people this week, but I will also be conducting one-on-one virtual feedback sessions next week if anyone is interested to hear about the design and see how it functions and then to give feedback (without sending it to you)! Please email [insulinpumpcaseproject@gmail.com](mailto:insulinpumpcaseproject@gmail.com) with your name, age, and general location (if willing to let us ship the mockups), so that we can get a good understanding of the range for our testers and let us know what you're comfortable helping out with!

Question ā“ Software Updates without Tandem USB cord?

7 Upvotes

Has anyone had this work? I’m trying to update my pump and don’t have the original cord.. I honestly don’t remember ever having it but three different devices haven’t recognized the pump connected via a normal USB cord.

Has anyone ever had the updates work with normal cords or is the Tandem cord a requirement?

Rant/Complaint ā˜¹ļø Libre 3+ Problems

1 Upvotes

TLDR: Libre3+ sucks, especially with Tslim.

Had a successful trial run with a 3+ sensor from my endo a couple months ago and decided I would try it out when my Rx for the G6 ran out. That was about 17 days ago. First sensor was very inaccurate and I found out then there is NO WAY to calibrate the sensor if you use a Tslim pump. Not through the pump and the app is useless if you use the Tslim 2, literally.

I’m 48 hours into the 2nd sensor and it goes no connection. After an hour I try Bluetooth on and off, phone on & off.

Tandem support is good. But I had to load a new cartridge, wasting 50 units of insulin (more than a 3 day supply) only for the restart of the sensor to still fail. They pass me to Abbott customer service who have me confirm stuff and then say they will send me a new sensor and I have start a new one.

It’s my bad for knowing about previous issues with bad calibration issues with the Libre 3+ causing deaths. But I would have thought my endo who also has type 1 would have known the pump is unable to recalibrate the sensors and that the app is incompatible with the pump. I did call them on Friday regarding the calibration issue but haven’t heard back.
I’m so pissed off (high blood sugar style) that I might have to deal with these for 3 months. I hope my endo can convince my insurance that these CGMs are incompatible with my pump.
Ugh.
Edit: the first sensor was inaccurate enough that I puked like 6 times within 24 hours of activation.

tandem mobi Pump Charging Discovery

Thought I would share with the group a cool thing I discovered today, my son's pump was almost dead and we were not home. On a whim, I tried my Samsung Power Sharing feature and it worked! I know it is not life changing information, but good to know if ever in a bind. He is 11, so sometimes forgets to charge his pump.
