Hello,
I've had mixed experiences with them.
They tend to take a bit of a sneaky approach to increasing their prices each year. Generally, it's in relatively small print, buried in an email covering a few topics.
That said, I've also found that they are open to reducing their charges for a year, if you indicate that you are going to leave. They don't like providing it, but they've a basic service that costs just over €32pm. In my view, that's still expensive for what they provide, but there are specific reasons why I have stayed with them.
They are extremely unlikely to come and remove the equipment, if you do ultimately decide to leave them. It's more trouble than it's worth. That said, there's another consideration for you - what good is it to you? I don't think the newer equipment can be used with rival service providers, but the older kit possibly can (there are various discussions on Boards.ie about it).
