I've had T1D for a very long time and been using insulin pumps since 2001. I've never previously had cause for complaint. I've been using a Tandem T:Slim since Jan 23 - I was persuaded by the Control IQ tech, but only managed to get that this year. - Control IQ mostly works brilliantly for me, and recent tweaks I've made have improved it further. The pump has to be on the same side of my body as the sensor but then it is pretty reliable. Yesterday 99% TIR. - Quality of sensors and tubing feels much less good than with Medtronic. I've had more occlusions than with any other pump, and I had to switch to steel cannulas which I hate. Tandem advised changing sites every 2 days which is a shocking waste of insulin, sets and money for the NHS. Poor quality of consumables also means that it restricts which insulins you can use. - cartridge process is ridiculously clunky - Supply has been more unreliable than at any point in the last 25 years which is scary. - The transition from Air Liquide to Tandem has been shockingly bad. They clearly hadn't lined up all the ducks before making the switch and have been unable to issue the normal quantity of consumables. - Customer service since the switch from Air Liquide, and with the above consumables issue is poor, and to me indicates issues at a process and corporate level. - - at no point has it been possible to have an online account to manage consumables orders. Medtronic had that over 10 years ago. It shouldn't be that difficult. I should be able to manage order frequency etc online rather than sending an email into the ether. - It is unlikely that I will renew with them later this year, which is a shame given that it is mostly a great little pump.

This is my second pump from them on the NHS. Both were the t:slim X2 insulin pump and I am now on the G7 Sensor. First off, the pump and G7 bluetooth connection is a bigger joke than that on the mobile phones. If it doesn't have perfectly clear line of sight for connecting forget it. Mine keeps losing connection so often, it's unreliable as a test for my Blood Sugar level. It can be sat in my bra at night, right next to the arm with the G7 on and keep dropping its connection. I recently had an email saying that certain cannulas, the ones I use coincidently, are unable to be provided and have moved me onto one choice only. A case of do or go without, or so it feels. They also changed the supplier of the consumables and their distributer. Before it was Dpd, now it is Ups. Their first delivery to me and I am not impressed. They tried once and left a card. I tried to access my account online and couldn't. I have their app but that said the number on the card they left wasn't recognised. I somehow managed to get access to a recording about my parcel that said it had been collected from an access point by.........It cut off without giving any name or further information. I then tried ringing the number on the card. First time, I was on hold for a few minutes and then............Nothing, I was cut off with no explanation. I tried again and after a good few minutes wait I finally got to talk to someone. He managed to inform me that my package was redirected to an access point for me to pick up. I asked if that was the norm for them? one try at delivery and then get the customer to do their job for them. Would I get another Tandem Diabetes pump? Nope, no way Jose.

My experience with this service was disappointing. I encountered several issues that made it difficult to rely on, and getting assistance when problems arose was frustrating. Communication was slower than expected, and the solutions provided did not fully address my concerns. For a service that plays such an important role, I expected better reliability, clearer support, and a smoother overall experience. Based on my experience, there is significant room for improvement.

I wish I could give this place zero stars. I was chatting w/ a dear friend tonight. She told me Tandem Diabetes Care (TDC) charged her ~$650 for a three-month supply insulin infusion set (IIS)... she found out later from her insurance company she should have only been charged $22 for the set; insurance urged her to contact TDC immediately for her $600 refund. She has called TDC a few times and still has yet to receive her refund.

After using TruSteel for many years, I had to use Autosoft because of the global shortage. The first think I noticed is the really poor design making me loose a lot of insulin by always have to fill a long tube. I was using 32in tubing with TruSteel because the Dexcom sensor signal is really bad and I have to move my pump from side to side on every site change. Autosoft offers 23 and 43in tubes. I ordered 43in thinking 23in would be too short, but with the poor design, I had to lose 18 insulin units only to get the tube filled. And since there's no way of changing only the needle part, I'll have to lose the same quantity on every site change!! I may use the 23in tubing , but I would still lose 8-10 units everytime. Do they understand that insulin is actually the only important part of the whole process and that everything else is simply optional helping stuff? For me, 10 units of insulin is what I need for my basal in a 12h period. As soon as TruSteel gets back, I'm not gonna buy this brand again.

Worst pump I've ever had. Can't silence the alarms, trying to reorder supplies is a joke, 1 out of 3 infusion sets actually works, and the AI is infuriatingly incompetent. My blood sugar is either rising above 300 or dropping below 40, never just in range. I had to buy 3 boxes of sites off a third party site, in my 28 years of being a type 1 diabetic I've NEVER had to buy supplies out of pocket, nevermind three separate occasions. I'm sick of pouring time, money, and energy I do not have into something that shouldn't be a problem in the first place.

Software update leaves you hanging. This is my life in the balance don't make me google to figure out how to get my pump working again after update.

I really like my Tandem T:slimX2 pump and the control IQ algorithm. My pump failed in January of 2026 and was still under warranty. They shipped me a new one. I thought that would reset the warranty, but it did not. I could not purchase an extended warranty. They want me to purchase a new pump when the replacement works just fine. Now in May of 2026, I find the pump is 3 days out of warranty. I wanted to update the version so it would be compatible with Dexcom 7 15 day sensor, but of course my pump version is 7.10.2 when 7.10.4 is needed. I cannot update the software since out of warranty. REALLY? VERY BAD BUSINESS. If you are considering doing business with this company, please know this upfront. They make you buy another pump for software updates even if you pump is a newly replaced based on original pump that has failed. I guess it's all about making money.
