It works well. It’s acceptably fast over Openvpn for what I use it for with the firewalla (I mostly have it for some geographic testing I have to do a occasionally) I have had at least 3 different companies at different time. I’d suspect most of them are reselling services that another company provides them wholesale and it comes down to how they provide the info. The main thing I would recommend is to look around and perhaps try a trial or two
