On the subject of Flygprestanda.
I too have never had any problems with them. We use the internet access exsclusively and have never experienced the problems that one poster here complained of.
You get what you pay for and there are better services with better support but they are more expensive.
By the way we have been to Flygprestanda and audited all procedures used to produce the runway data including obstacle charts etc. In fact they are due another one soon.
In these days of SMS any quality department would be well advised to be auditing all third party suppliers.
