Tell us about yourself!
How well does it work in a brightly lit room? Nice work!!! My wife is also a nurse RN. She works with cancer patients so their veins are very fragile and the ones they have left are very small. I will make one for all the RNs to try out, but my wife and most others are good at finding the veins. You said green was the best to use for the case you know why right?
So any dark color will work. Thanks.
