Yes I did, and do not "look back"...
Look pumps have a grand total of three advantages period. Micro-dosing, and the sign wave bolus thingy. The ability to give tenths of a unit of insulin has advantages. Most problems we all have are caused directly by excessive insulin usage. Whether caused by unusual-rapid absorption, or by simply using too much at one time for whatever reason(s). IF we had the ability to inject/bolus tenth units, or half units, life would be a hell of a lot easier because of it. Worst case scenario, golly gee, I used two tenths of a unit too much ooooopsey. not three units, or five. That ability to micro-dose is a definate advantage.
The other advantage is the sign wave ability. In english the ability to distribute the dose over a far longer time than the moment which we inject/press the buttons, delivering the insulin into our bodies. With that ability you can eat pizza. However beyond that fairly narrow ability I have no clue/concept what possible use it actually holds? Surgery perhaps? Do not know.
The final advantage is an electronic memory. You have a device that will keep track of exactly when and how much insulin we use. Fine as far as that goes, but until it also records with clinical accuracy the food intake, the mechanic errors the pump had shortly thereafter... (e.g. the dose never got absorbed, the line kinked, etc.), and you have the capasity, the ability to transfer all that data somewhere which will analyze the data and help us severely tweak things... its pretty much entirely worthless information
Beyond that, pumps have definate disadvantages FAR worse than any issues with daily injections. Causal DKA, delivery errors, severe adhesion problems, site infections, the beeps, alarms, supply costs, the extra/backup supplies, the external "bionic device" we cannot be separated from for long without directly causing trouble because of that separation. The interference which wearing an external device does cause either with water or intimate sweaty activities
Its NOT the pump which makes them good, its the insulin which all pumps use which gives them the claimed "flexibility". (And its a mistaken claim)
No thanks, no pump again, until they work out the massive systemic and fundamental kinks. Second generation, internal pump, closed loop system, then maybe, until then NOT A PRAYER
