My old "Siemens" Gigaset C 4xx has for 9 years his mind had thus given a new phone here. Impressed by the exuberant reviews and test reports, I ordered this one. Fast delivery by Amazon, as usual, unpacked, connected and tested. - The assessments in various magazines are all from past years. The buttons are now made of plastic, small and fiddly. For art inspired contemporaries like the SL 400 still have what graceful, for daily use, it is, in my opinion, inappropriate. Each key will be individually precisely controlled, the setting switches with even more meticulous. There's nothing with fast times to enter number. But just for a phone was supposed to be built? The SL 400 is not. It is too small and, well, "verstylt". If one also takes into account the still, then you should definitely try out the hands-free setting. The problem of modern flat screen TV's also here finds its way. Just creepy !! even though you have made sure that it comes from a recent production unit and was directly connected to the Fritz box. My conclusion: nice to look at in a modern "hospital wall". Not suitable for frequent callers, or even in the commercial sector. Despite possible cashback - returning!
