Here is your answer from one of the guys above:
I'm still using cFosSpeed after these 2 years.. mainly to let my browser work well while torrenting. And also after this I might go into VoIP while torrenting too...

So far the latest version v.4.24.1420 seems to work like a charm 

Carry on the word guys and please do buy original. It doesn't cost that much for a lifetime license. Remember, its lifetime... no annual subscription.

*edit*

Oh btw, sorry I didn't update the 1st page, the price for cFosSpeed naik harga already. I think its 11 euros now
