The one thing I love about my Animas pumps is I have had the best control ever. The smaller basal and bolus increments have helped me a lot. I use very little insulin for a type one - but even less being on Victoza. I can use anywhere from 15 units to 30 depending on the carbs. My basals are .45 to as low as .325 - which I can do with Animas. My lastest Ping went a full 3 years without a major problem (the internal clock died - but I did not realize it except I had to reset the date everytime I changed the battery.) The pump itself, worked great! Animas swapped it out for me in December and my warranty is up at the end of June.
I also like the lithium battery - and being able to use alkaline if I am stuck.
The other reason I switched to Animas from Medtronic was as you said - the luer lock connector. Having the freedom to try different infusion sets is a big plus. Also - I love the color screen, I can see it in most lighting - except bright sunlight, Medtronic has just kept that awful menu system with the problem circles like - forever! Their screen is so tiny....
I am intrigued by the T Slim - I also like the POD - but because I use so little insulin - it would be a waste changing that out every 3 days. Plus - I am not sure I want a big egg shaped thing on my body. I can pretty much hide my pump and many think it is a pager.... LOL. The tubing has never bothered me - gotten in the way - sometimes - but pretty easy to hide.
I am wondering how the rechargeable battery would be for me... since I am not always good about recharging my phone. I think it is rarely quick though like my Samsung S5 - quick charge and I am good to go.
Oh - I have reused the reservoirs sometimes - but mostly do not. Sometimes, if I need to change my infusion set and there is insulin in the reservoir, I might refill the reservoir and reuse it. It works fine but reservoirs are probably the only things cheap with this disease....
