There’s a YouTuber who does gun reviews that I watch occasionally, and I wish other reviewers were like him. He pays for them with his own money, and Patreon money. If the gun is very popular he’ll do a short video and label it initial thoughts, and then eventually he’ll do a review after he’s shot 1000s of rounds with it over weeks and months. If he notices something wrong, he’ll look online to see if anyone else has similar issues and mention things like “I have an original model, which has problem X, manufacturer Y has since addressed this, and fixed it, and the community agrees it is no longer an issue. So look out for the first year release of X if you want to buy.” Overall he does an excellent job of separating his opinions from selling points.
