I used it with an 11GB game and it took 50 minutes, 26MB/s which varies , and I use a laptop it discharges in 2 to 3 hours of use
I do not find 25 Mbit/sek slow. That is plenty fast and should download Harem Hotel in an hour and a half.
Plug in your laptop when doing a long download. Have a nap while the download happens, read a book, watch a movie or go for a walk.
Anyway, I still do not see how transfer.it would help.
