Not sure why seen so much bad feedback here. Using BTGuard for more than 8 years. I ran into problems about 3 times. Figured out it was a software upgrade. Following their setup instructions for PCs/Linux phones works.
I used BTGuard for about 4 years with no issues and very professional service! You need to understand that BTGuard will NOT support unethical action, and nowhere in the service contract for the BTGuard service plan(s) does it state they will . So if you have technical issues while trying to accomplish an unethical act, they will not even respond or get involved in your unethical actions willingly, for the simple reason is that they do NOT desire to be an accessory to your unethical action(s). So don't expect Sales or Tech. Support for that. Yes they advertise that you can achieve anonymous torrenting, However, that does not imply unethical torrenting. The only issue I have with VPN service providers is that there is no real definitive way to know if they are actually allowing access to your VPN communications to a third party. The bottom line is, if you are involved in unethical activities, do not expect support from honest company's.
I used them for several years without too many problems beyond when I actually had a question I needed to be answered by this outfit they never bothered to respond to my emails. One day, while connected to BTGuard, my IP was leaked to my ISP and I received a notice from Cox that I was in violation of their user agreement. I questioned BTGuard about this and I was immediately suspended and my account was closed. What the hell kind of treatment is this? And of course, they didn't bother to respond to my question as to why on earth I was suspended. At this point, I moved to TorGuard and never looked back. I've used TorGuard for 7 years. They offer a reasonable price and excellent service and outstanding customer support. I see BTGuard is still in business despite their lousy customer service and their limited functionality as discussed by the author of this article and there don't care attitude about their customers. Makes me wonder how they have any.
