I got a Genteel Lancing Device after several friends in USA told me about it.
I LOVE IT, and YES its totally pain free! .... this has been a life Highlight. Even though I've only used it for 1 week .... after 30 years with T1d my fingers have never felt better!! My hands feel new.
Sure its more expensive, but for me, its well worth it for how great my fingers feel only after one week.
Ive been using it with their custom made Genteel lances, as I was warned that it will hurt if I use standard ones.
Its great because you can take blood from anywhere (except for hairy spots because the vacuum cannot hold).
I've used it in all these sites; the palms of my hands, my calf, my thighs, my forearm, my cheek, and totally painless everywhere.
