It is a small display format for smartphones. You shouldn't be severely defective in vision, and you won't see much detail on the screen and only have a small resolution available. For that, the device should be small and handy, easy to transport.

Gigaset Communications GmbH is a manufacturer of DECT phones, tablets and smartphones, headquartered in Germany and originated from a subsidiary of Siemens, but has been part of Arques Industries since 2008.

The market shares in the smartphone range are just as low as the amount of test reports. The achieved ratings are average (as of 2016).

75.37%: This rating is not earth-shattering. This rating must actually be seen as average, since there are about as many devices with worse ratings as better ones. A purchase recommendation can only be seen with a lot of goodwill, unless it is about websites that generally rate strictly.
