Should I use a VPN router with Tails?

Hi folks,
Perhaps a user could gain additional privacy and anonymity by using a VPN with Tails? From what I have seen, perhaps the best way to deploy the VPN is with a VPN Router (such as the GL.iNet Beryl) to connect to the host computer that is running Tails. Please give me your thoughts on these ideas. Thank you.
