I prefer the B-D Ultrafine system. I HATE lancets, especially when they are powered by something spring-loaded. They have a relatively large blade that, in my opinion, hurts more than any other diabetes regimen. I gave up on the whole concept about twenty years ago, when I started just using an old syringe. It's much less painful and perfectly sufficient---especially now that blood requirements are so much smaller. I guess I'm just a wimp, but I wouldn't go back to lancets, even if I were paid to do so. I guess I'm just a wimp.
