The customer service is horrible. My pump stopped working and they told me I'd get a new one the next day. They didn't ship it and can't tell me why. I was with Medtronic for 35 years. They were much better with their service. Very unhappy

I have had the Tandem Mobi for less than three months and it has already burnt out the motor and it had to be replaced. Additionally, I landed in the hospital due to inconsistencies with the pump. I have tried to return this product for over a week, and they said they submitted the return. Haven't heard back from my local rep as she is probably upset to lose some commission and also the technical support team has been less than helpful, except for one person Shane. I have asked them to send me cartridges also because I will completely out tomorrow, and they shipped it ground so I will be without a pump for a few days. This is very dangerous and should be addressed. I have tried everything, even trying to post on their twitter for help. No reply. If anyone has any other ideas please let me know, I really need help. Thanks.

BEWARE. My wife tried to upgrade to Dexcom G7 with her t-Slim pump but couldn’t due to the fact that her pump warranty had just expired and the software release on her pump was not current. Tandem would not offer her any support !!!

Tandem Lego type syringes and cartridge screw type connectors are just junk.Be prepared to lose insulin in the exploding weak connections! Tandem customer servicecwill graciously refer you YouTube and "Resource Guides" that provide no useful information. This used to be a 5 star company. Medtronic has another new customer.

I find the Tandem T-slim X2 pump itself to be very good despite the cumbersome steps to refilling it with insulin, but a good pump is useless if there aren't good infusion sets to go with it. I have 26 years of experience with using an insulin pump with infusion sets. I have never been more frustrated with it than I have been for the past year since switching to Tandem. I have tried nearly every infusion set they have and none of them work as well as the Medtronic infusion sets. I understand the infusion sets are primarily made by the same company, but either it is a poorer design or poorer quality materials. I'm lucky if I get more than 24 hours of good delivery from a Tandem infusion set before it starts leaking, and that is if I divide large insulin boluses into a couple of smaller boluses because anything more than about 5 units at one time is more likely to leak. (I got the idea of dividing boluses from a social media group where other Tandem users were having the same issue.) This also means having to take insulin at least a half hour before eating so I have time to do more than one bolus and it has time to absorb. If my insurance company would allow me to, I'd go back to Medtronic immediately just for the superior infusion sets that helped me maintain more stable blood sugar control. Both Tandem and Medtronic have pros and cons, but again, a pump is useless without effective infusion sets and Medtronic's were much better. If you take very little insulin such as no more than about 4 or 5 units of bolus at a time, are on a low steady basal rate, and can afford to change the infusion set every 48 hours, you'll probably do fine with Tandem T-slim. Otherwise, the infusion sets will likely be an issue.

The tandem source online portal is a joke, as well as their customer service. I haven't been able to order supplies online due to some error, and when I call Tech Support like they recommend, they just ask me to clear cookies and switch browsers a couple times. Then they say a Tech Support rep will reach back out in a couple days. No help at all, and then when I call to order supplies, they aren't available on weekends.

My pump failed last week 05/21/24 I was about to die my sugar went above 500 and it happened again
Now my insulin levels is too high pump shows nothing but hyphens
No one pick up the phone in Tandem
Should I die?
You should connect me to support asap

I’ve had a Medtronic insulin pump for the past five years. I recently switched to the Tandum X2 slim. I couldn’t be any more disappointed with this pump. I’ve had a lot more low blood sugars since I started using this product. It is often that I’ve had trouble, changing the infusion set and the insulin cartridge. My suggestion is to do your research before switching insulin pumps.

They sold me a product they don't even have in stock. They were quick to take my money for the down payment. They made promises regarding to shipping that never happened. I had originally thought I would go with Medtronic but the endo office talked me into this mysterious Mobi pump that they don't even have in stock. They told me I was an early access customer which I interpret as I'm a beta tester. No one could provide an acceptable solution other than I have to wait until they get pumps to mail out. Supposedly that's a week away but I sincerely doubt this will happen. I was duped into getting this pump. I was promised a pump this week and nothing. I had to call THEM to find out that this product is not in their inventory even thought I was told it was in stock when I placed this order. I'm furious. Supposedly shipping takes another week so I'm not going to see this pump for at least two weeks and then I have to have training and who knows how long that will take to arrange. I spoke with their escalation department and got NO satisfaction. I don't want a refund. I want a pump. I'm taking seven shots a day. If they don't have this Mobi pump (and frankly, I don't care a whit about the size of the pump), then they need to send me another pump. They are ridiculous. I spent so much time on hold today while they scrambled to try to find out what is going on. How can I trust this pump when the people who make and sell it can't seem to figure out how to do either of those things. I bet my payment plan starts for a product I don't even have.

No one cares I’m a type one diabetic who has a tandem pump . I had received errors for my dexcom that say invalid transmitter id . A call to dexcom and a call to tandem and well nothing was found and I called tandem back another day. Tandem had me restart another sensor this is number three . So tandem calls dexcom and they get me sensor replacement and new transmitter . Yeah that part didn’t happen 5 days later it’s Thursday and still nothing so I call tandem after dexcom let me know they were sending out sensor! Tandem says sorry I understand well I said no you don’t I am a single mother of three kids that is a type one diabetic with hypoglycemic unawareness, I need their product I get sick without it with terrible control. I check every 2 hours yes round the clock vet I don’t feel like dying . I’m a nurse and it affecting my ability to work . No one cares we can make an email that was a supervisor with attitude and no answe. Well I left holding the bag and they pretty much told me to pound sand. I am going to blast this company from here to hell and back I asked for resolution .On top of it of the transmitter is the problem or I will have to get a replacement pump. So I’m screwed and getting sicker by the day ! Watch these people are just about the money and don’t care about their patient safety or prioritize my health over their profit!

worst thing ever, it is always a problem with it and it never works. I recommend using pens instead of this. Whatever you it will give you tinnitus and it never works like it should.

Consistently late supplies deliveries! So unsafe!! Every single time I have ordered supplies, I end up having to bum a sample or two off my doctor. Insurance denies order if I order too early, but even when I pay extra for two-day delivery, inevitably, it takes WEEKS for them to even ship the order! I just had to call them AGAIN because I am using my last infusion set and I was told that even though I ordered over a week ago (after an infusion set accidentally got yanked out and another went bad…so yes, this time it’s a true emergency), there’s no sign of when it might ship. At the point I placed the order, that rep told me that (again) the order would be expedited and should ship in the next day or two. The rep today told me there’s no way for him to figure out why it hasn’t shipped. I asked what I’m supposed to do over the weekend and the guy was so dismissive. Not his problem, I guess. Think I’m going back to Medtronic. I like the tandem pump better but I can’t keep taking these risks!

I constantly have issues with my pump and they won’t replace it (it’s 3 months old!) and twice tonight my cartridge only filled to 50 units and not even with the plus sign. Two days ago I filled with 250 units. No plus sign again and the meter read 150 units for two days. No plus sign. The first time I changed the cartridge tonight it wouldn’t even slide in/click into the pump. This design is terrible and so is the injection of the insulin into the cartridge! IM GOING BACK TO MEDTRONIC! 28 years on that pump and customer service and tech were TERRIFIC! I’ve been on hold waiting for tandem tech for 30 mins now and my pump isn’t working and my sugar is climbing!! This is ABSURD

Support is impossible to reach. Wait times are too long and they take forever. I expect fast times.

Out of all the insulin pumps I have used, the T-Slim has been the most frustrating and wasteful pump. It does not have the simple technology to tell you the cartridge is not full enough until you have wasted at least ten units for the fill tubing process. And don’t get me started on customer support. Use the Omnipod.

I am so sick of having to waste insulin for my pump to recognize there’s a new cartridge. Please change this feature!!! I do not always need to spit out 10 units of insulin to the trash every time I change my cartridge. Sometimes my cartridge runs out before 3 days. Sometimes I am running high and use it up way before then. Sometimes I have to replace the infusion but not the tubing because it gets knocked off my body. Who are you to decide what happens to my insulin and the money I paid to stay alive? I had a Medtronic pump before and if they had a pump with a closed system and slim profile I swear I would have never switched to tandem. Unbelievable. I also want to mention that less than a year into owning this pump after 5 years with Medtronic, I had to get a replacement sent out. What in the world are you guys doing? From what I see all you are doing is exploiting diabetic peoples desire to live a normal healthy life by flashing new tech around as if it is actually worth it. Oh and so much for their extended infusion sets. I don’t get a single day longer the regular, more affordable, Medtronic sets. I feel lied and betrayed and if I weren’t stuck in this money pit, I’d get out and have another company manage the future of my existence.

I developed an allergy to the t-steel cannula but no one could figure that so I had to wait 3 days to speak to a nurse to figure that out and another week to get the sample new infusion set to try it out. If they do not know something they just refer you to your endocrinologist who usually does not know. Very frustrating!

I have the pump for 1 year. This is not a good pump. My previous pump AcuCheck was working perfect but supply infusions are not available to US.
Anyway with this new insulin pump my A1C increase significant from 4.8 to 5.9.
The infusion set is not very efficient. Normally I need about 30 units per day but with this pump needs about double the insulin delivery. In addition the insulin delivery acts very slowly. If you High in sugar will take very long to finally be back in normal ranges.
I am not using carbs for insulin calculation.
Using this Tandem pump you will not be able to sleep anymore. I turn all the warnings to vibration, but still very annoying. Always is non stop beeping. From low power, low insulin, infusion side changes, high, lows, sometime pump thinks you may get low or high generating alerts.
The phone app can't reach the cloud. If you set it works, but when travel to different WIFI or network will need to put your E-mail and password again.
For the pump interface I will give 1 Star only. To program a bolus you need to go in 6 steps just to go there to input a number. Pump touch screen is not capacitive sensitive, so you actually need to press on the screen to work. If you miss 3 times the pump screen locks up and need to start again.
Only good thing about the pump is stopping insulin delivery if you are getting low in sugar.
I do not recommend this pump.

Terrible customer service, I have been waiting weeks to send back the X2 pump, they are VERY slow to send the Auth Code. They Just want to sell the unit, after that they ignore you.

I have to say my experience of the tandem tslim has been great
I had been on a different pump for over 8 yrs and was worried about change but
The change over was simple and straight forward the rep was very helpful
Once I was able to access the dexcom6 and the iq control the results were outstanding
My hba1c dropped to 4.9 within weeks!!
Never in 40 plus yrs have I had a result anywhere close to that! Lowest ever was 7.9
I am incredibly happy with all aspects
the customer service has been straight forward and reliable
The rep has been great! Thanks Amy
Everything has been beyond my wildest dreams
Honestly nothing negative to say
Brilliant and amazing!!
