Hi! I've been using the Medtrum 200u pump since April 2024 and have been very happy about it. Very easy to set up, replace and apply. I use the "alternative adhesive" variant of the pump which is more of a bandage-like adhesive which I personally prefer. I don't find it bulky, despite bumping it into a doorframe or something alike every now and then.
Some things I'd like to share based on my experience:
- Although it
feels fine when I lay on it when I sleep (I prefer using my arms instead of abdomen), it will often leave behind a lump which takes multiple days (often around a week) to recover. This is obviously not always the case for everyone, but it is for me.
- Very rarely, the pump's needle will pop a blood cell which will seep into the pump and sometimes even drip out. Do not worry! I have never had complications or inconsistencies with the pump when this happens. The only thing to keep in mind is that the needle may have a more difficult time retracting (when you use the sim card pin). Just keep wiggling it inside the little hole and it'll eventually pop out. Make sure you clean the pump base afterwards!
- I have also experienced a handful of bad pumps (as
@JC Durant stated above) in which it would often error out with occlusions which then shuts the pump down and forces you to replace it right then and there. My worst case was when it happened twice in a row within 2 days, and then again 2 days later. That's 3 pumps in 4 days! It does warn you beforehand that it is having issues and will shut down if it doesn't get resolved quickly, but it is still a pretty bad feeling when it happens. I have not had this happen in over a year.
- Speaking of which; Medtrum contact and support is amazing. I have never had trouble contacting them and received many back-up pumps after sending a form regarding faulty pumps. They have always been extremely helpful over the phone, coming from someone who has called them several times, especially at the start.
- The pump has an 8-hour grace period. After 72 hours, the pump will tell you it is time to be replaced and will forcefully stop working after 8 more hours. While this was done for flexibility purposes, I personally use up the entire 8 hours if I'm able to do so. Note that during these 8 hours, the app will consistently remind you (using alarming sounds) that you're in the grace period. When your pump fully stops working, either through an error or from expiration, the pump itself will start beeping too, just in case

A lot is put in place for our safety.
- I recommend not to set too many basal time periods. It will get confusing quick and you will lose track of what is and isn't working. I was recommended to have 3 time periods at most. After 3 years, I have found myself to do very well with a single time period.
I'm sure there's more I could add but I can't come up with anything else at the moment.
I am also using Libre 2 alongside Medtrum's pump but I look forward to switching to Medtrum's sensor once it has been approved by my insurance company.
I hope this pump will treat you well!
