I am currently on a t:slim pump. I've been on it for a couple of months now. I currently like the t:slim much more than any pump I've been on (and I've been on pumps for about 15 years now) and can tell you right now that besides the demo issue, NONE of Jenna's points are valid and/or correct.
* As far as demoing the t:slim, I'm not sure if you can use one for an extended period, but I called Tandem and a rep met with me within days to sit down for a few hours and let me do whatever I wanted with the pump. Just call them and ask.
* It shows BOTH the remaining insulin and battery on the home screen.
* You CAN do a simple, quick bolus with one hand and one button without looking, the same as with an Animas, etc.
* The reservoir isn't hard to fill at all.
So, I'm not sure where Jenna got her info... Regardless, it is a great pump. The Animas Ping sucks, frankly. I had been an Animas customer for years and their customer service has gone drastically downhill. In addition, they outsource all billing department calls to India. Tandem on the other hand is a company that is owned by private investors who have a vested interest in the product. They have every reason to offer the best possible service and for me, they currently have.
Their pump replacement warranty is better than the other companies in my opinion. They will overnight a pump 24/7, 365 days a year if you have a problem. The pump is very intuitive to use. There is a quick bolus setting that you can use to deliver a bolus where each button press is either based on units of insulin or carbs. I keep the quick bolus set to units and the bolus "calculator" like on other pumps set to carbs. That way I can either calculate a bolus, or just give a quick bolus without looking if I know how much insulin I want.
The only issue that I have come across and not found a workable solution is that Apidra insulin hasn't worked well in it for me. I kept getting occlusions. I tried many possibilities by switching out both insulin brands and infusion set types and it came down to Apidra being the culprit. That's kind of a common issue so it seems, regardless of the pump though.
ALSO, Tandem has announced that it has officially partnered with Dexcom to include their CGMs in upcoming product updates, etc. just like every other company. Animas has been promising to release theirs for YEARS: www.tandemdiabetes.com/Content1Col.aspx
In addition, Tandem has also partnered with the JDRF to develop a dula chamber insulin pump: www.tandemdiabetes.com/Content1Col.aspx
Really, Tandem is on the cutting edge and changing the way we look at insulin pumps. Other companies will be playing catch up. Feel free to message me if you want to talk in more depth. I'm not at all affiliated with the company, I just really like good T1D technology!
