there is no problem with the stethoscope itself, but I was very very disappointed with the Caribbean blue color. I understand that the online picture is going to appear slightly different on each devise that its open on, but this color was wayyyyy off from what I thought it was going to look like. When it arrived in the mail, I thought maybe they had sent me the wrong color, but no, it looked like a plain blue color. Yes I ordered a Caribbean blue, but I was expecting it to be a nice lighter color like that picture shows. like I said, nothing wrong with the stethoscope itself, its just the color was not what I wanted and due to the fact that I had it personalized, they will not honor their satisfaction guarantee policy. so now im stuck with a color I don't like, unless I spend another $200 on a new one.
