I agree with Zoe.
I've known people who used OmniPods then switched because of problems (stopping delivery, getting knocked loose/off playing sports because they sit too high, etc.).
I was on MDI for many years as well and had severe swings in BG levels due to dawn phenomenon. I too used Lantus and Novolog.
After doing research I decided a pump was definitely the way to go. I didn't want the OmniPod because of what I heard and the comments of close friends who tried them. At the same time I was concerned about the "tubing." I didn't care for the the idea of being tethered. Would the tubing kink and stop insulin delivery? How am I going to sleep with this thing? I believe these are the kind of thoughts which make the OmniPod appealing. I looked at information on all the pumps available in the U.S. comparing their features. I viewed many diabetic user web sites reading their critiques of whatever pump they were using. If they switched brands along the way it was interesting to find out why.
After sifting through all this I decided on Animas for a several reasons. One I thought was important was it had the smallest increments for both basal and bolus deliveries. The smaller increments would allow me to more finely tune the pump to my needs. Another reason was the pump was waterproof to 12 feet for up to 24 hours. I knew people on other brands who put their pumps in plastic sandwich bags when taking a shower or had to take them off. That's a nuisance. I also like to swim. Some pumps would have to be disconnected while doing so. I heard comments about good customer support from Animas. Since they are part of Johnson & Johnson, who makes LifeScan glucometers, my reasoning was customer support would be similar. I spoke with my doctor and informed her I wanted to go on the Animas pump. There had been no prior discussion so she was surprised to say the least. Her recommendation was the Medtronic pump. I told her my rationale for choosing Animas and she agreed. She had Animas do the training for me.
My fears regarding tubing developing kinks, etc. were unfounded. That's not to say if I intentionally folded the tubing over and clamped it with pliers it wouldn't stop delivery; it definitely would. I not an issue in normal use including sports. You do need to make sure it's routed so it doesn't get caught on doorknobs, etc. I did have that happen once early on in my use.
As Zoe mentioned any pump will do the job as long as it is properly set up. It took about 3 months to regulate my BGs. Animas has a very good book available on their web site called "My Insulin Pump Workbook;" (http://www.animas.com/about-insulin-pump-therapy/online-education-training). I downloaded the book before I made my decision and did all the exercises. As far as the controls are concerned they are specific to Animas pumps but the concepts are all the same. It covers expectations, doing basal testing, etc. I found it to be very helpful.
The journey of moving from MDI to a pump has been well worth the effort and the few bumps in the road along the way. It was THE BEST decision I ever made regarding my diabetes and care.
