To put it as polite as I can in a family friendly manner to meet forum rules - It's rubbish.
If fact, I would say it is even worse than the Traveline Wales site, quite an achievement.
I assume that it is smart phone friendly making it unfriendly for those in the dark ages sat at desks.
The service updates screen slides behind another screen making it opaque and impossible to read the service updates.
It still has a hissy fit because I won't let it save my location.
