I feel like I gave the Ping a good try, wearing it for almost a year. In the end, though, it just wasn't for me. Oh, I love the technology, the color, the precision. After switching to the Ping my average TDD dropped from 29U to 17U. It really did seem to make a difference.
The problem turned out to be the form factor. No, I'm not joking. The shape and size were bothering me. In fact, I didn't realize how much until I put my 522 back on. Then all the little things that had been bugging me became apparent. I thought I would love the Ping meter remote, but in practice I almost never used the remote function. I wasn't checking my bg as often, but I couldn't figure out why not. I never even used the carb database, since it worked differently from how I'd been told. Little things abounded - like after I tested I would immediately forget what the number had been.
When I switched back to my 522 and UltraSmart, the problems disappeared. I have no trouble remembering the number from the UltraSmart (and yes, I know that's weird). The 522 and its clip are flat on the back and much smaller than the Ping. The display goes the other way, which makes it easier because I like to wear my pump on one side.
With all this in mind and the fact that my MM warranty expired last year, I decided to upgrade to the Revel. It's been rocky (although nothing like the ordeal I went through with Animas), but I got my new Revel and hope to start on it soon.
