The best product to be released in recent years the amount of times I've been stabbed by a nurse just for them to miss one of the veins is incrediable.
there are still years to go before the same tech is actually used in a real world medical setting
Google can fast-track it.
still needs to be thoroughly tested before anybody is going to use it
