Most tool reviews I’ve seen in the past were pretty lackluster. Lotst of talk about gimmicky features and aesthetics but nothing really discussing the actual engineering behind the product. I recently came across youtube user AVE and his excellent tool reviews/teardowns where you get to see what really makes a makita or dewalt tool better than a harbor freight tool. He methodically takes apart tools highlighting material selection, gear types, bearing sizes, manufacturing quality and more. You even get to see a lot of parts through a USB microscope. I highly recommend takinga look at his reviews.
