Seedbox.cc VPN?

Hey everyone, ive got a question about Seedbox.cc's service. I am thinking about purchasing a seedbox from them (its been a long time since ive had my own box) and it really seems from my reading throughout the site here that they are the most reputable service, with probably some of the best offering... I will be getting their 'bat box' most likely.

My question is regarding their VPN service... when I purchase a box service with them, do I get to have a client/use their VPN as my computer's main VPN as well? IE; I use ExpressVPN right now and although their service is good and works well for me, if I am to pay for a monthly seedbox and they seem to include VPN with it, will that cover all my grounds, or is the VPN just for usage with the seedbox server itself and I can't access it with my computer?

Id love to know, and if so, what someone's experience with general cruising around the web/speed their VPN entails you. Thanks!
