The softclix/multiclix uses much better technology in the springing action of the lancet than the ultrasoft does.
The ultrasoft moves from side to side (vibration) when it springs forward into your finger, which is what causes the pain. the softclix/multiclix lancet devices don't have that "vibration", they go in, then they come out, in a straight line, which causes much less discomfort. It's good technology.
I wont be winding my lancet on everytime, maybe once a day. So ill use a new drum each week. You can reset the lencet drum if you really need to. but you're not supposed to so im not gonna say in open how to do it (it's not difficult to work out though).
So it's more about the technology in the device than the new needle that causes less pain!
Testing in the dark... it will always be difficult until the meter companies put an LED light or something on top of the meter that points towards the end of the test strip. At the moment, i use the ultrasmart which has a nice backlight, then i cup one hand over the display so the light reflects off my hand to my finger/strip so i can see where the strip is in relation to the spot of blood on my finger... it's not perfect but it does work.
