The facility of Gigaset will only work if it has online access to the Gigaset server but repeatedly fails for several days. During this time they have no function, it also has no evidence of a failure, only one LED flashes to himself. Only when you try to log you realize that that's not possible. Calling the support number then gives the flippant reply that it just does not go and take a few days until the functionality can be restored. For a message on the home page is not enough, so would save the calls and could be misunderstood as a customer service. This often fails an alarm system and therefore does not fulfill its function seems the manufacturer to matter to me as a customer, it is certainly not the matter that can and will affect my buying habits.
