Yeah, if you have to test regularly then your fingertips end up hurting like hell (for a while I had to test 10+ times a day).

You also have to keep buying new needle drums/cassettes as well as glucose strips - not sure if this system cuts down on disposable parts?

They'll probably still hurt. This thingie basically shoots you with a teensy tiny bullet and then slurps the resulting blood.

I thought most people used the insulin pumps now, with the lancet for testing?
