BT Smart Hub

I am awaiting BT Infinity 2 to be installed and it comes with a new Smart Hub. I already have a Smart Hub and wondered if I could give a loan of it to my neighbour who is having trouble with his adsl BT broadband to try to see if it solves his issue. If I do this will it cause a problem using my spare Smart Hub myself in the future for my setup?

No that will be fine.

The only issue is will a new smart hub actually turn up?

Thanks BatBoy for the info. Will wait until the new Smart Hub arrives.

The smarthubs do not work very well on ADSL btw. Quite a few bugs
