I don't know anything about this particular MDPI journal, but my experience with other journals published by this group is a bit worrisome. They often (a) ask me to review papers that have nothing to do with my research activity and (b) ask me to be an editor of special issues that, again, are in fields unrelated to my work. I can think of no well-respected journal that does such things. The other side of the coin is that I know of no serious researchers who submit to, or read, MDPI journals, despite the fact that they have some journals that would, based on title alone, be relevant. There is a bit of discussion of whether to consider MDPI a "predatory" publisher at https://en.wikipedia.org/wiki/MDPI https://en.wikipedia.org/wiki/MDPI. None of this need reflect on the paper in question, of course. Perhaps this particular journal is of high quality. And, even if not, perhaps the paper is of high quality.
