seedboxes.cc are good and very fast seedbox, i personaly have one But the speeds are not as they advertise (10Gbps). you do not get 10Gbps on seedboxes.cc, and why? because they only have 2x 1Gbps lines on the servers. they advertise 10Gbps because their competitors do the same, its just a marketing technique. on the 10Gbps plans you only get 1Gbps [100MBps]
Bat Box, Gremlin Box, Vampire Box, Zombie Box
the plans above, the max down link you get is 100MBps (1GBps) on hot torrents, the UPLOAD is always as they advertise except on the Red Dragon Box on this plan the upload is 100MBps same marketing technique as the dowload.
note that 10GBps lines are way way more expensive as the 1GBps line.
best regards
