Only you can say whether it is good value for money 😎 - but there are some good deals for new customers ATM... so you could just go for it. You have a 14 days post-activation cooling-off period, in which you can just cancel it at no cost to yourself - so cant lose really - try it and see.
Dont cancel any current connections until VM is installed and activated - there are occasional "issues"
Yes it needs installation by Tech visits... one of which involves drilling through a wall, and fitting an internal wall box and then connecting/balancing the equipment.
