I had a Tandem tSlim X2 insulin pump and it failed. Called Tandem and the support person confirmed the pump failed---repeated Error Code cartridge would not seat and deliver insulin to pump. How sweet! Tandem sent me a refurbished pump and it could not even be charged...it was 'DOA' or Dead on Arrival. They must not have any quality control Whoever heard of shipping out an important medical device without checking to see if it works? The original pump, still under warranty, suddenly failed by stopping all insulin delivery without warning. Lost several cartridges trying to satisfy the Error Code 20 warning to replace the cartridge. This wasn’t just an inconvenience—it was a potentially life-threatening malfunction. I promptly contacted Tandem’s customer support, and they arranged to send a replacement. But what followed was an even more disheartening turn: the replacement pump was entirely nonfunctional out of the box. It would not work at all and could not even be charged. Two consecutive failures, particularly for a device entrusted with sustaining life, raise serious concerns about quality control, reliability, and patient safety. I expected Tandem to offer equipment I could trust; instead, I was left scrambling to preserve my health and manage a crisis that should never have occurred. When we use devices like this, we’re not asking for luxury or convenience—we’re asking for a lifeline. Tandem, in this case, did not deliver. I really liked the Tandem insulin pump when it worked...before failure. I did not like getting a dead replacement pump Not much excuse for that. UPDATE I tried my son's Tandem USB cable and it worked to charge the replacement pump The Tandem cable I had worked on my old pump but would not work on the Tandem replacement pump One of life's mysteries

Called the support line got a person who acted like they didn’t know anything about pumps. Call lasted 50 minutes without fixing the problem told me I’d have to wait for someone to call me back the next day at 330 I also feel like their supplies have cheapened not working keep getting an occlusion error have to change sets until finally the third set started working.

On top of all the complaints that others have already left, who ever decided that "you have to pump at least 10 units before stopping" needed to be programmed into the device should no longer be allowed to make company decisions. How are you guys going to make Metronic look good?

Not Trustworthy company. I have type one and their pump was faulty while I am on vacation. They promised to overnight me a new one since I am leaving this location on Sunday. This was on Friday morning. I now find out on Saturday afternoon that the new pump will not be here until Monday afternoon. That means over 3 days with having to give myself constant injections and costing me a ton of money in hotels since I cannot leave. I had Medtronic for more than before and they always had years and every time there was problem they had a new pump to me within 6-12 hours. I got more help from FedEx than Tandem who said I should just wait until Monday and offered no additional help.

I have been with Tandem for over 12 years. The customer service, help, call back, rep help, shipping supplies times- have all dropped down to 0. I used to think Tandem cared and I loved this company and recommended them all the time to friends/ friends of friends with kids who were diabetic. Older folks that got type 1 after COVID, etc. Since 2024 I think they are just out to make your life harder being a diabetic. Once customer service rep asked me to prove my 400’s and high sugars over 3-4 days as they couldn’t send me supplies that had defective bending cannulas in my body when inserted. They have no idea how terrible you feel in 3 hours o high sugars. A screenshot of my pump readings that only read 24 hours was not enough. Supplies are always delayed. Expect 3 weeks not 10 days as they say. their expedited shipping which they charge you for takes 3 whole days to process before its shipped out. 3 - 5 more days to receive it The cost of their supplies is high and has never been been covered by any insurance. They promise to call back but never do. I. The last 7 days I’ve called 2x for a team expert to get back to me and no one has. For a company that makes their money off ‘helping diabetics’ they are terrible at helping. I can see why their publicly traded stocks have been tanking for a year. FYI just tried the tandem Mobi. Amazing job making it smaller. In the 3 month trial period the charger has already stopped working, and the Mobi won’t turn on. Thank gosh my TSlim X2 hasn’t been returned yet, hopefully they won’t penalize me for not returning the old pump. It didn’t sound too good when I was on the phone with them today. Tandem I know you tell me the calls are recorded every time, and refuse to share the call with me- Please actually listen to the calls. Review readers if you get on the phone with them please record it for yourself and mention it to the person you’re talking to that you will be recording the conversation. Guys, dont let the #jonasbrothers AD with Tandem Diabetes fool you! We don’t get the same treatment as a celebrity type 1 diabetic.

If I could give them 0 stars then I would. I’m currently pregnant and my pump stopped holding a charge! Of course it was out of warranty then so my doctor put an urgent order in for a new pump. The order was placed 12/31. I called on 1/3 to check on the status and I was told they never received anything. I even have the letter in my chart so that was frustrating. I called my doctor back and they put in a new request. I had to call them back again today, 1/10, only for someone to let me know they are working on it now. So no one was working on my urgent referral for a week and a half? Absolutely insane.

I've had my tandem pump for a year and a half. Before I was using medtronic. Never had malfunctions with medtronic but I did not like how my bloodsugars ran. So i wanted to try tandem. I run great on this pump but I recently had a malfunction error out of no where with tandem. I had to call customer service and they sent me a new one the next day. The new pump they gave me already is malfunctioning as I just started it. A cartridge error. It keeps saying replace cartridges. I called and I have to send this one back. Also I am 8 months pregnant and my bloodsugars are running horrible. I'm not using these pumps anymore and going on the Omnipod after all of this.

I have a T:Slim 2. The algorithm is clunky, not allowing you to tailor to things like the length of time insulin is active, or what blood sugar level you want to target (below 7). It makes adjustments to insulin based on how recently you last entered insulin - a stupid step when you are eating at a buffet, for example. I also received emails offering software updates, but the instructions were not correct and so not one of the updates would work. Tandem did not reply to questions asking for explanations.
