I'm convinced it is the worst product on the market. The point that nurses are non skilled is the whole point here. It's too difficult to use for them and god forbid they have one of our ultra sounds because you can't see the needle. It's actually pretty dangerous and I wouldn't allow anyone to put that thing in me or a family member. Oh and thanks for tying our maintenance to this product. Most of my customers stopped using it cause the first version was really really bad and now I know have to rebirth that business and I have to grow more on top of it?! This product has ruined relationships, hurt people and pissed of a to of reps.
