I have already bought two 10G plans and while the speed increase is only ~20-30 KB/s, I’m glad you have a service like this. It really helps me max out my connection. I just wanted to offer some praise for this implementation. Thank you for this. 
I think it simply should be stated that the speeds won’t get any faster if the connection is already maxed in the first place, even with VIP. If you paid for a 3 Mbps plan, then 3 Mbps is just the theoretical maximum your connection can move at. It won’t become any faster. VIP won’t help that.
Anyway, I’m really grateful for your client.
