I think it is obvious that many ‘content creators’ have (often undisclosed) financial interests and conflicts, and I am sure that the same applies to LH- his ‘admiration’ for some Sage products is conspicuous. Credibility aside, I think that he is a mediocre Youtuber, mainly because of his communication style and poor articulation which makes it difficult for me to enjoy any of his videos (although he seems to have made some progress since he first started uploading content).
Irrespective of that, what I find funny is that he struck a particular nerve here with his Niche review. It is fair to say that many people have a soft spot for the specific grinder, either because it is a British success story and people have been involved in its development, or because they own it (myself included as of last week), or simply because they consider it a great grinder totally worth its money. Not sure that LH would trigger such a debate with any other review..
