as by defination opinion articles are "Opinion articles present the author’s viewpoint on the interpretation, analysis, or methods used in a particular study. It allows the author to comment on the strength and weakness of a theory or hypothesis. Opinion articles are usually based on constructive criticism and should be backed by evidence. Such articles promote discussion on current issues concerning science. These are also relatively short articles."
so i'm confused about writing an opinion about some technical device will be considered as opinion article or not ? and will it be recognized by journals worthy for publication or not ?
