    • Love it
If you're looking to get into tech work or just need a good set for around the house, look no further. This set contains an amazing amount of value. Good quality tools, decent plastic trays for organization and if you misplace or damage anything it's nothing a quick trip to Lowe's won't resolve!

Style: NEW 298 Piece Set
This tool set offers fantastic value for money and provides a wide range of tools that surpass the ones you may have been accustomed to.

Compared to higher-end brands like Milwaukee or SnapOn, this set comes at a much more affordable price point, making it accessible for many users. Despite the minor room for enhancement in terms of contrast, the set's performance and durability make it a worthwhile investment for both DIY enthusiasts and professionals.

    • Great tool set.
Great starter set for aspiring mechanics. Bought for my son to work on his jeep. Craftsman tools have worked well for me for decades. Are they sn*p on or m*tco? No. But they don’t require a second mortgage to buy them. And they are far better than the cheap sets at the discount store.

    • Tool trays are labeled white on black and well done
This set comes with 4 flat boxes in 1 tall box. In each flat box is a tool tray to perfectly organize all tools, they are labeled white on black and even come with a clear also molded dust cover. The trays are 22" x 11" and fit into the narrow drawers of a Husky tool cart. Amazon shows: Foam inserts help to keep the tools organized while in storage. The Craftsman web shows: Foam inserts.
