In use, I have two models from Gigaset (E48, C629). Unfortunately, it's me this time really been difficult to buy a high-quality Bluetooth model. I've looked at all the latest cordless phones with recessions of Gigaset, Philips and Panasonic. The choice was the S810. The plastic makes a very cheap impression. Therefore, a star deduction. Otherwise, it's okay. Maintenance is no longer Siemens quality. An alternative does not exist apart from the competition.
