I was so excited to get this device for my iPhone, but that slowly turned into disappointment. First of all, it does stay into the phone, it falls out, so you literally have to hold it into place while trying to read the card. It works well if you do feel like holding it in the whole time so that it doesn't fall out. It is a rose gold color which is very pretty, it has a nice keychain loop on it so you can put it on your keys or wherever to keep it close to you. Also in order to use this, you do have to download the witstick app, or it will not work. So overall, it works, but they need to figure out how to get it to stay in the iPhone so you do not have to hold it in place the whole time.
