It works wonders. My ISP started blocking bt trackers and I ended up here. I'm using Ajato (São Paulo, SP, Brazil).

For the ones having issues there might be a quite simple solution:
*** follow the guide provided in this topic but edit the files manually, not using the GUI, and remove the # symbol before the User-agent string. I"m not home right now but I'll try to post what my headers-request file looks like later.

For the ones wondering about the speed, I could get more peers using DHT and my speed kept at 40-50kb/s (max is 64 kb/s). After I used this method the speed didn't change (but I managed to connect to the trackers and get more peers). The method doesn't interfere with speed. If you got problems then it is your ISP. Try Encrypting your connection without allowing non-encrypted connections (i.e. for utorrent set the encryption to FORCED and mark the box DO NOT ALLOW LEGACY CONNECTIONS or something like that).

I hope it helps
