A pump does not remove the need for shots and as for the accuracy, well that is up for debate. You still have to learn the bias of the readings it generates versus the manual test. It is a lifestyle change from shots, you will be moving the point of insertion quite a bit and some sports may be better served with a shot regimen.
There is one nice feature of having a pump, with an always attached device you can get warnings when your asleep which can save your life. Many of these devices will either beep or vibrate or both when you enter a danger range. Even if it does not alert you it could alert whomever your sleeping with; even pets will take notice and possibly wake ya.
Last note, most insurance plans expect the pump to be replaced after a couple of years so find out up front how many years before you should expect to replace it.
