Carson, possibly a name chosen for the similarity with the well known Carton brand...
In China there are many bino manufacturers and most make for several brands. Often the same design (occasionally the same optics) used for a well known brand are also sold to "house brands" . That porro prism design is also cheaper to make, so usually better value than the narrow roof prism version. With binos what you see is what you get, but test them out before you buy.
Good comment about the Leica, I have recently misplaced my 8x20. Ouch...
