Clock came afloat, unfortunately, they could be connected to any mobile phone

The clock came very quickly, looks visually great, despite a lot of function not clunky.
Unpacked and charged. Sorry, no connection with tablet or mobile phone was absolutely produce. Not even with the new cell phone's, no chance. All mobile phone's / tablets (of course, all of Samsung) showed a coupling, but the clock has continued to search.
So to get, unfortunately, the installation screen does not extend and the clock can be used in any way. Not even to telling time.
So I got it sent back.
That went smoothly and the refund was easily (albeit much more slowly than the costs).
