You can stream your favorite channels on multiple devices at the same time! This is made possible by getting a multiroom setup, meaning having a multiple m3u subscription.

Multiroom gives you 10% discount on second subscription (if you need 2 rooms, you pay 2 times the subscription and get 10% discount on the second).
So let's say in you have a Forrest 1 year and is getting 2 subscriptions for 2 devices (sample only, different rates apply to each subscription):
1 device = 60 euro
2 devices = 114 euro (60 euro on 1st device, 54 euro on 2nd device)
