Many people have used STO Express. I don't know what you think of STO Express. However, I would like to say that based on my personal experience with STO, I think it is the worst, most shit, black-hearted and shameless express company I've ever seen.
I just used STO once, but that didn't stop me from making this worst evaluation on it, and I'm very sure about this evaluation and will never change.
Just let me tell you the process, and you'll understand why I was so angry.
