Well he isn't sponsored and and he does them from his own pocket. So that is why I support him. You aren't going to get lab quality without muddied waters of funding coming from hands that might influence the results. For what you are getting you are actually getting decent quality. I'm an industrial engineer myself and while his methods aren't completely scientific they are practical in the sense you can recreate them at home. That is what he tries to do. He does tests that you can recreate yourself.
