I worked on a crop farm the last two years and anytime we needed to fix a tractor or anything and everything you could ever imagine. However I myself learned that cheap quality isn't made for heavy machinery; so before I left for the day; I always made sure to bring my Craftsman 108 Piece Mechanics Tool set. The couple times I forgot it; I would either get stranded or I'd have to have someone bring it to me. This tool set outlasted five huge farming tractors; plus many other problems. I've had my Craftsman 108 Piece Mechanics Tool Set for just a little under two years. However, due to the top craftsmanship and great performance of Craftsman's products; I will never buy any other brand ever again. Thanks Craftsman. I give this tool set two thumbs up. My older brother has bought strictly Craftsman's products since adulthood. Now I understand why. He's been a journeyman electrician for over twenty years now. And he has never used anything else.
