Dear Marcus Engdahl,
I don’t use it for the following reasons :
- The spatial resolution of the “quick view” or whatever it is called is super coarse. I cannot distinguish my area of interest easily, which is not the case when using the official sci-hub
- It is super easy to script the download of an entire dataset in the official sci-hub. using aria2c.
Again, this is just one-man’s opinion of the subject.
