Been pumping for about 24 years and all of that time with Medtronic. Just switched to Tandem ( huge change for me). Really do like the T:Slim but wonder about bolus when lower than target. Medtronic's wizard would subtract to adjust for the lower…Continue

Turning the t:slim off?!

Hi Everyone,I apologize if this has been covered before (and also, I can't find my user's manual...which probably isn't a good situation!). Does anyone know if it is possible to turn the t:slim completely off? Or do I just need to wait for the…Continue

How long does it take to download the data from a T-Slim either to their software or Diasend? I currently have an Animas Ping & it seems to take forever.Continue

Infusion set bent cannula

So I spent 7 hours in ER today. Mild DKA. Changed my infusion first thing this morning and 2 hours later BG was almost 400. Changed the set again and notice the first set had a 90 degree bend at the end, so I thought that was the problem. My BG…Continue

Best Inset to use with my Tslim

I am very close to giving the go ahead for a new Tslim, but I am totally new to pumping and have a couple of questions. I currently use the I-Port insulin delivery method. Here are my questions:1. Is the Tslim a good or bad pump? 2. What is the best…Continue

Hi all, in case there are those out there who didn't know this, the excellent (and free) Diasend site now not only supports uploads from Dexcom units but also t;slims. I tried this the other day having read that Tandem and Diasend were going to work…Continue

That is awesome. I will have my old pump as a back up. But I do not have any issues with going with the t-slim.

Comment by willne1 on March 20, 2015 at 9:47am
Welcome... I do mean I charge it from 90 to 100 in ten minutes or less. Just wanted to make that clear.

Thanks Willne 1!

Comment by willne1 on March 20, 2015 at 9:03am
I'm a newbie at pumping... But on a day I change my inset on top of everything else I normally do mine goes down about 10%. I plug it into my laptop for about 10 minutes or less and it's back to 100%.
Comment by Susan Van Abs on March 20, 2015 at 8:49am

I have a question about battery life between charges. I am looking at the TSlim as my possible next pump. Am currently on an Animas Pump - where I can use two different types of batteries. I get over a month on a Lithium battery - but am concerned about the waste of using disposable batteries.

How long do you get from a charge on your pump? D you get a few days or close to a week? Do you charge it a little bit every day? I am impressed with the battery life on my Dexcom - so am wondering how the pump compares with all the bolusing, basaling and other things we demand from a pump?

The hospital diabetes educator was telling me she had met with the tandem ppl and soon there would be a software update for our t:slims that we would be able to download....has anyone else heard anything about that?
Comment by Susan Van Abs on March 8, 2015 at 7:45pm

I am looking forward to seeing a demo someday on the TSlim. That is most likely going to be my next pump. Not even considering Animas at this point. My warranty on my PING ends in June. Animas has not earned my business...

Comment by Estel Hines on March 7, 2015 at 9:42am

Hi gang, I am on my third week of my new T:slim (5 years previous with Animas Ping), I like it just fine, the IOB on the first screen is great, and I usually change everything each time, when I get down to 3 or less units of insulin. I then discard the cartridges in my sharps container. I am a happy camper.

Comment by diaman on March 7, 2015 at 9:36am

I'm about to get a new pump. It's down to t:slim or animas vibe. This is my 4th pump (most recent was an Animas 2020). Just saw my endo yesterday and he said his patients who use t:slim like it if it's their first pump but patients don't like t:slim if they'd switched from another pump. Still, I'm leaning towards t:slim and comments here help. Has anyone had experience with trying to return a t:slim if it doesn't work out?
