Though you’re soaps reviewed all tend to be rated above average, I think the commentary in the video really balances it out some. You do verbally voice some negative points of the soaps often, though it may not always reflect in the score. Sometimes it’s the opposite, where you’ll have had what looks to be a good shave, then later during the scoring some surprise points will be dinged.
Overall I think you at least give good reasons behind you’re general scoring, enough to be on the more objective side. While you could talk about lower scoring soaps (which might be a good idea, particularly more widely recognized/experienced classics), you don’t necessarily have to go through the hassle of shaving with them just for us.
