Since this is my first pump, I have no comparisons. But I really like the fact that I don't have to carry a pump and a Dexcom. That I really love. I know a lot of people didn't want the G4 because it didn't have the latest Dexcom technology. I don't care that it's the G4 and not the G5. I don't have a smart phone. I didn't get my Dexcom receiver updated because I knew I'd be getting this pump.
I like that I don't have to have injections all the time, that's a big plug. I've had several bad sites already, which I didn't expect so soon. I guess that's a plus so I know how they feel.
For me the biggest problem is I have to wear the pump on the same side of my body that the Dexcom sensor it located otherwise it gives me a out or range warning. I'd much rather wear it on my left side as, but I can adapt.
I didn't have any problems sleeping with it. I discovered that I have to have the 23" tubing, because when I used the 43" after an a few hours, the site became bad. So I just use the infusion sets with the 43" tubing when I have bad sites.
I had one bottle of bad insulin, which was a first for me in my 50 years of being a juvenile onset. That was something else. I know the bottle was bad because I had to get a new bottle at a site change. My site never bothered me, and when I woke up my blood sugar was high, not 300 high, but high enough. I had a bolus to cover it and a hour later it was still rising. So I injected myself with a bolus. It was still rising, so we (my husband and myself) decided to open a new bottle and mark the "bad" one, and inject myself with that. Once that one started lowering my sugars, we did a complete change since we knew the insulin in the cartridge wasn't any good. I called the insurance company and after talking to costumer service they connected me to a pharmacist and they sent me a new bottle.
