T:Slim - Two weeks in...

Justin has been on the t:slim for two weeks now. You can read all about my initial thoughts here.

Justin is still loving it, of course. I feel is has its pro's and con's.

When it comes to being user friendly, I'm not sure it could get much better. The touch screen for adding carb amounts and bg #'s beats the thumb aerobics it took to get all that info into the Ping... AND if you mess something up, you don't have to start all over. BONUS!

Changing carb ratios and basal rates... super easy. You don't have to button push through the entire list just to change one rate... choose the one you want, and tada!!
I do have one complaint about the way this is set up though... On the ping the basal rates, i:c ratios, ISF and bg target all had separate screens for you to set them up. All of this info is in one place on the slim. So say Justin's basal is .625 from 7am to noon, but I need a different i:c ratio for breakfast and lunch... I have to set up a whole new block within the profile... so both blocks will be exact basal except for the i:c ratio. This is by no means the end of the world, but I can foresee it getting confusing when Justin is trying to read off all the settings to the Endo(as he does at every appt). The CDE even questioned why I had like 3 blocks with the same basal rate... and it was because either the carb ratio or the ISF was different.

Again, not the end of the world, but I prefer them separate. Maybe I just like the info in different screens because all the numbers, all at once, can become overwhelming.

I consider this a safety fail for the younger users... It doesn't subtract insulin to correct low-ish bg's. For whatever reason, the slim does not start subtracting insulin until they are 69(or below). So if he's 70... I have to manually subtract insulin from the suggested delivery so that he doesn't end up low(ish) again. This may be a HUGE challenge when school starts. Justin would have to know his different sensitivity factors and targets(they vary during PE etc...) in order to do this on his own. On top of that... he actually has to remember to do it in the first place. Not sure why Tandem would give the pump the capability to subtract, but not let it base it off the target rate rather then what the standard low bg may be. Maybe we were just spoiled since the Ping did this for us.

Site changes... holy mother of crap they are a pain in the ass!!!! I'm not even going to abbreviate it... that's how bad it is. As easy as the touch screen feature is... they sure didn't mimic that ease of use into the cartridge fill. Granted, I have waisted a little less insulin with each cartridge change, but the process is lengthy and frustrating. To be honest, if Justin didn't love it so much... this may have been a deal breaker for me.

Apidra(sigh) - when they said it didn't work in this pump, they weren't kidding. I was in hopes that we would be one of the lucky ones that didn't have any trouble, but no such luck. For us, the Apidra stops working around the 18th hour in the slim. This means extra site/cartridge changes... kill me! Only six vials of Apidra to go... I'm trying not to throw away money, but I probably won't last that long.

Charging the t:slim... one day, I will actually remember to plug it in while he's in the shower. One day! The battery does last a while... thank goodness. I think I've only charged it twice since he started wearing it two weeks ago and it hasn't died yet. Can't say the same about the meter though. It will be nice not to spend all that money on batteries anymore.

Speaking of the meter... I still love the Verio IQ(aside from the need to charge it thing). Strips take way less blood then the Ultra strips and I have not had an error yet. I managed to score a Verio sync too... so I'll have to try and compare the two when I get a chance.

I am in hopes that the site changes will get easier. Cross your fingers for me.

Sounds a bit like a PITA to me...right now we are deciding what pump to switch to and I am not too thrilled with any. I think part of it is we have only had experience with one and that is what I prefer because I can do it at 2am with no problems. We'll see though, we're trying to get Isaac to help with the decision but he doesn't care about anything other than color. However, it is good when they like what they're using so I am glad that Justin is happy with the tslim, hopefully it will help encourage him to do those little things like you talked about with reverse corrections when needed. Man, he is so mature - what big steps you've made through the years. I know we'll be there someday but it seems so far off. Hope your summer has been off to a great start :)

I switched to t:slim last year (was on Medtronic for years). I do love how easy it is, but I agree that site changes take FOREVER. And one time I pressed the wrong button and even though I had just gone through the whole process and insulin had dripped, it made me do the whole thing again. I've been using Apidra though and just recently found out that it hasn't been tested with the pump and isn't recommended. It's worked fine for me, except toward the 2nd or 3rd day...then I seem to run into occlusions and high numbers. I'm switching to humalog soon to see how that works. Good luck!

Thank you so much for this review. I need all the insight I can get!!! I'm not sure what our future holds, but the warranty is up in December...
