if commercial broadband
definitely not recommend HKBN
my experience
个packet loss/jitter 好大
2013 experience, 个客call france H.O.
幾分鍾 cut 1 次call
But
唔代表 residential broadband 差
1. customer base 大 , hot/recent subject 多人BT
2. 大把人 (e.g.dom) 話 netvigator 玩game 差 / 斷線
thus, it all depend how bad experience you have with BN now
and whether you can still endure or not
