I have been using the rdp for most of the day and here is my short review.
Download speed is great from every site i tried. It doesn't go under 10 mb/s but is usually around 20-30 mb/s
Upload to FS/HF/FSC is also very good, especially if you upload multiple files (i was getting 30 mb/s)
The upload speed to RS is not that good, around 3 mb/s with multiple files.
I couldn't get mega manager to upload anything so i didn't test MU speed
Unrar/Rar is very fast.
There are a lot of programs already installed on the desktop.
All in all, i recommend this service.
