Seedr is immensely helpful for me in getting all my legitimate torrents like ubuntu iso, etc.
Even the free tier of Seedr packs a punch. All the files can be downloaded without any restirctions on speed of the download.
In free tier, only size limitation of 2GB is there which i think is the required amount for most people.
If you want more space, you can subscribe for upgraded storage.
Checkout Seedr here.
This is a frank review of Seedr.
Cheers,
