You can put it on any 5 devices. It's a bit of a pain if you want to change these devices and you can only change 1 a month without contacting support
I too got this but for like £15. I use them at home and I get almost gigabit service so I don't get a massive drop off with their service. Most of the time when I'm on my own thing I use my VPN service out of habit. There's really no performance drops. (just commenting to vouch that I also have really good performance considering the low cost).
You can use the connections on any device you like, they have no idea who owns the device. (y)
I've been using for about 18 months with no problems....
Anyone know if this can be shared with family? Or tried sharing with family members?
