It looks crap download limits are bad to say the least and for some really strange reason they have 18 separate servers for all the groups. so if you grab an nzb from here you will need to find out which server caries that group before you can download it.
it also doesn't state its retention or completion rates so god knows what they are. and according to domatas you are limited to 3 connections at 35kbs each which is plain terrible. he is also wrong in claiming you can get 1050KB/s since alot of the servers wont carry the group you want your more likely to max out about 300 kbs.
