FWIW my opinion is that I see nothing whatsoever wrong or unethical with Peter calling attention to his own products, in his invariably understated (as opposed to over-the-top) manner, and given that he invariably accompanies those mentions with a manufacturer disclosure. In fact, given that his mentions of his products can be presumed to often be useful information not only to the OPs but also to others who may read the threads, while also of course potentially being of some benefit to his business, I fail to see how these kinds of posts can be viewed as anything other than mutually beneficial "win-wins."
