+The Reviung41 is a 41 key keyboard designed by gtips, it is a slightly larger
+version of the popular Reviung 39. These "split non-split" keyboards offer a lot
+of features split keyboards have in terms of comfort and ergonomics but do so in
+a single-piece package. Many people consider keyboards in this style easier to
+travel with since you don't have to manage two halves and there is of course no
+need for a TRRS cable. This board sits somewhere between and Atreus and Corne,
+and it is extremely comfortable to use.
