My Review of the Tandem t:case

On the surface it seems that designing a case for an insulin pump should be an easy task. The new t:case for Tandem t:slim pumps demonstrates that it is actually more complicated than that and that it might be impossible to design one case that will make everyone happy.

Two weeks ago the news spread like wildfire around the Tandem community that we could finally order the long-awaited t:case. A limited selection of colors was offered at that time, but the full spectrum (Black, Blue, Olive Fatigue, Pink, Purple, and Turquoise) is now available on Amazon. Some colors are in stock with others back-ordered until August 5. The Tandem online store continues to show most colors as “Coming Soon” but keep checking. The introductory price of $19.95 is guaranteed until August 31 after which the price may increase to $24.95.

The previous t:clip case was available in fun mix-and-match colors. It looked great, but had major problems with a top heavy design and the tendency to fall off user waistbands. The clip was too bulky for pocket use although some women liked that it was easy to attach the pump to their bras. Frequent breakages and replacements were common. I personally hated this case. Some users liked the t:slider case and I used the removable part of that case in my pocket.

The t:slider case has not been available through the Tandem online store for many months and the remaining stock of t:clip cases shows availability only in Flash Green and Sunset Orange. Leatherette cases are still offered and include the t:flip, the t:holster, and the t:wallet.

One thing I like about Tandem is the importance of design. The t:slim is a sleek and modern pump and I don’t think that Tandem would be satisfied with a case that wasn’t equally attractive. I also think that after the track record of the flawed t:clip case that it was important to “get it right” this time.

So did they get it right?

Yes and no.

The Yes:

The case is made out of what seems to be a very strong plastic and there is no flimsy clip or hinge to break. I think that the case will be durable and provide excellent protection for my pump.

The cutouts make a lot of sense and allow the user to charge the pump and change cartridges without removing the case. (That is good because it is not easy to remove the pump from the case.) My photo below shows a view of the back of the case with the many cut-outs.

The removable clip allows the pump to be worn in a vertical or horizontal orientation. For those  who carry the pump in their pocket, the clip can easily be removed. However, it is so low profile that you won’t be bothered by just leaving it on. The clip is made of stainless steel and seems unlikely to break or bend.

The No:

In my opinion Tandem made a mistake in how the clip attaches for horizontal wear. Those who wear the pump horizontally usually do not want to remove the pump from their waistband to see the screen or program pump functions. Therefore it makes sense for the pump to be oriented upside down so that when it is lifted up it is right side up for the viewer. The t:case orients the pump so that it is upside down when the user lifts it up. This is a big problem for those who are using the t:slim G4 for their CGM data and for those X2 users who will soon be able to see their Dexcom G5 data. Another annoyance about this clip position is that the tubing comes out at the bottom of the pump which increases the opportunity for tubing to hang down below your clothes and to jump out at doorknobs.

The Meh:

The t:slim screen is turned on and off by pushing the silver T:button at the top of the pump. My guess is that I push that button 30 times a day. For unknown reasons Tandem added a plastic cover over this button on the t:case. Previous cases just have a cutout. Unfortunately I found that the button cover made it difficult to turn on my pump. Sometimes it worked the first time; other times I had to push the button 4-5 times. I have arthritis in my hands and am unwilling to tax my joints just to turn on my pump.

Fortunately this was a problem easily fixed. The photo below shows my X-ACTO knife solution.

I found the clip to be quite secure when wearing the pump horizontally, but as I explained above, lifting up the pump to an upside down view doesn’t work for me. IMO the clip is slightly too short when wearing the pump vertically and is not as tight on my waistband as I would like. But it is okay and I know to be careful.

Tasks like removing the pump from the case and changing the clip orientation are not straightforward and no instructions are provided with the case. Fortunately there are instructions available on the Tandem website but that link is not included with the case.

User Feedback on Facebook:

“After wearing my pump all day in the new case, I have to say, I really like this new style case…ALOT! “

“I love my new (pink) case so much I now also have a black one and a purple one on backorder lol”

“Okay, so I may be the odd person out, but I’m not feeling the new case. I don’t like the clip…”

Addressing the cover on the silver T:button — “I’ve found mine getting easier to press- although it’s possible that it’s just my hand getting stronger”

“I just received the new hard case they have designed. No more plastic clips!! Has a metal clip and you can change the cartridge without taking the pump out of the case. I love it!”

“Anyone else annoyed that the pump is upside down with the new t:case when you look at it?! Why didn’t they put the clip on the other side?!”

Addressing the clip placement for horizontal use — “My understanding is they took in feedback from a lot of pump users so either no one thought of that or there were technical limitations that prevent it or they ignored the user feedback.”

“I love it! It’s way more comfortable to wear, and it doesn’t dig in like the old style did. And best of all…it isn’t top heavy anymore!”

“I really still don’t like it. I can’t put it in the center of my bra, which is where I normally wear it, and it won’t stay on my waistband. Putting it in my pocket makes my pants slide down and/or the tubing hangs out.”

“Just got the new clip for the pump but it didn’t come with any information on how to put it on can anyone help me out with this??”

“How do you flip the metal clip on the new case?”

“It is great. I can use the clip on a pair of shorts or put it in the pocket of my trousers without removing the clip.”

“My new T:case came…. WHEEEEE!”

Summary:

I am happy with my t:case. It is compact, functional, and attractive. Although I think the clip design makes a horizontal orientation an unlikely wear for me, I am satisfied to use it vertically or in my pocket. I have previously written that my problem with false occlusion alarms on my X2 was solved by using a case. Whether it is a temperature issue or the cutout for the vent holes, the cases have completely eliminated my alarm problems.

I think that no one could create a case that would please everyone. We each have unique needs and opinions. The t:case is mostly a win for Tandem, but IMO the horizontal clip position is a big problem—especially for integrated CGM use. I know that Tandem had many customers test drive the case and I wonder why the horizontal wear issue was not fixed. Also, did they consider older and disabled users? If it were not for my X-ACTO knife, I would not be able to use this case because of the difficulty of using the T:button. And I am not really that old or very disabled….

Here is a short instructional video about the t:case. I am currently using a black case but also ordered a pink one. In terms of color, I think that the video depicts the color of the cases much better than the Amazon photos.

 

Please note that this post discusses the t:case for the t:slim, t:slim G4, and t:slim X2 pumps. The t:case 480 is for t:flex pumps and is available in black and purple. The t:case 480 only allows a vertical orientation because of the larger insulin cartridge.

  1. I am very pleased that I won’t have to remove the case when changing cartridges.The very thing that makes the pump stay in the case securely also makes it hard to remove the pump from the case.So this is great. Although I haven’t ordered one yet (I am glad to hear they are now available) I agree that having the orientation of the pump be “upside down” makes a lot of sense. My former pumpers group in San Diego (had to leave the group cuz I moved 1000’s of miles away – not because I didn’t value the group) were probably among the beta testers.I’ll have to contact them and ask about the orientation thing. Thanks Laddie for
    posting

    • Kristina, I would be very interested to hear what the beta testers say. You’d think at least one of them would have encountered the problem. One Tandem user on Facebook suggested that the decision might have been based on maintaining the strength of the case and not have too many cutouts near each other.
