The control panel makes it easy to set up bandwidth restrictions for different users, services or devices with ease! It's also very flexible in terms of what you can do as far as limiting certain types/protocols like HTTP vs HTTPS etc (as well as setting custom rules).
I would love if there was an option where we could add multiple IP addresses at once instead having them each get their own separate line item which isn't ideal when adding more than one address per user - but this may be something they're working towards? We've been using BWC since around 2009 so have had many years experience now & haven't really found anything negative about our setup yet either way just thought i'd mention here anyway :).
