Have a tandem tslim x2, and might be a silly question but has anyone had their pump fall off/slide off their pants when they go to stand up, and it falls fast and bounces up and down like a bungee cord, while still attached to you at the insertion site, and spins around 100x in 1 second real fast like a top ? And maybe bangs into a nearby cabinet hard…would any of these things cause damage or malfunction to the pump where it woukd over deliver or leak somewhere!!!

If it doesn’t pull the cannula out, don’t worry about it. I’ve cracked the screen but otherwise, I’ve never been able to damage the tandem. I’ve had 3 over 10 years.

I’ve dropped it many times, including the rather painful yo-yo drop, and also onto hard surfaces. I don’t know that I’ve achieved the impressive spin rate you describe, but I would say that if it seems to be working, then it is working.
The nightmare that you describe where all seems well but it’s actually over delivering or leaking with no alarms or anything seems extremely unlikely. If you broke it, you’d know.
That said, I’m not an expert. You could describe what happened to customer service if you wanted.
Something tells me you aren’t alone.
I’ve had mine do unbelievable acrobatics and which onto hard surfaces and I think it’s pretty robust.
Then, for $6,000.00 it should be able to withstand a space launch and operate in a vacuum and in the absence of gravity.

You’re fine. The pump does so many safety checks constantly and will alert you if there’s a delivery issue. I do the bungee thing more often than I care to admit. Usually happens if I fall to reattach it after bolusing, and it’s just been sitting loose during the meal. Then I stand up… and scream. It hurts!
Part of the FDA review process involves shipping your device off to a 3rd party testing facility that runs it through the wringer doing durability testing, which includes drop testing. They’re designed to take a beating aged keep working.
Plus, don’t forget about the whole Micro-delivery Technology thing that set Tandem apart from other tubed pumps in terms of safety. You’re completely isolated from the reservoir of insulin. It’s pretty much impossible to get unintentional insulin out of it.

Sweetgal88, Next time capture a video. That would be hilarious!
My cannual usually pulls off when that happens to me. I got the rubber case on amazon to protect the pump and make it easier to grab. It was way to slippery. I also got the holster to clip it on my belt or pajamas.

Not necessary. Pumps are expensive mustly because relatively few made and sold, not because they are better made. If Apple sold as many iPhones as Tandem has sold pumps, they would cost 10-20x what they do now and be at least as easily broken.
I do think they are tough. If the infusion set doesnt come out, it is fine. If it were damaged, it would almost certainly alert.
My pants have elastic in the waistband, with the pleats hidden at the tops of the front pockets. So they have a opening inside the waistband. I loop a rubber band around the tubing, then put the end through the loop before attaching it to the pump. I loop the rubber band over the front button and button it to keep it in place. Then I drop the pump into the pocket through the top. There’s plenty of space to put it out of my pocket without excess slack.
Sorry! I just realized I didn’t make that readable. The link should work now please let me know if it does it.
Clever, TJG, clever, I am always amazed the ingenious work arounds we can come up with. When I got the pump I had concerns about what to do with it sleeping, My solution was to get these mildly elastic “invisible” belts that I wear 24/7. They came 4 in a pack so it is easy to wash them.
Because I am a bicyclist who mounts expensive electronic equipment on my bike I was familiar with these Garmin lanyards. I found a way to connect one to the pump case and then loop it around the belt. They are elastic which is helpful. Having the ability to bolus from my phone app is really helpful.
I got belt like that with a previous pump, the H-Tron or D-Tron maybe? I never used it. I just clipped their case to my belt. For biking, I just put the pump the left jersey pocket. Meter was in the center pocket, food in the right,

I always have used Medtronic pumps, and used their holster clip. Hooked over my waistband of pants, skirts, jeans an pjs. Perfect!
Many timed hit the floor or the wall. It is built like a tank and seems nearly indestructible
Not to worry
Takes a licking and keeps on ticking
If you use the 23” tubing it won’t ever hit the floor
