I bought this tool set and I think it was a great purchase. It comes with several useful pieces that are good for different jobs around the house or in the car. The tools feel sturdy and the case helps keep everything well organized. I liked that everything is neatly arranged and it's easy to find each piece when you need it. For the price and the number of tools included, I feel it's worth it. I recommend it for having a basic kit at home. 👍🔧

Stripped a nut, this fixed in quick. Went on to strip two bolts, ditto. Good value.

Its as to be expected- blow molded case wont latch (plastic too thin)- arrived all mixed up. Both the die holder and the tap holding bar died first use- steel on tap holder jaws bent and stripped threads, screw on die holder so soft butter might hold better- I am afraid to replace with stronger screw- thread gauge thinner than I'd like- but works. Tap and dies...seem ok quality. I needed a metric set for repairs- and will use my other sets holders.

Worked perfectly! Had to drill into an old rusted bolt in my washer machine and used these to create a new threading so I can use a smaller bolt to fasten everything down. It worked as advertised!

The sizes stamped on the tool is incorrect. I used the m12 1.5 tap but it seemed too small so I miked the result and it was about 11.1 mm or 7/16. not 12 mm (m12). It looks like they used a 7/16 but stamped it 12 mm. I haven't tested the other sizes but if this one is sooo far off the others are not to be trusted. I would like a refund immediately and for other customers to be aware.
