Good tools for what I need them for

Great to use such high-quality tools. I was happy to throw away my China made tools that I had used before.

Typical Klein quality tools. Not the least expensive out there, but if you use your tools daily these are a bargain. They also have a lifetime warranty - no questions asked replacement. This set has a wide range of sizes, comfy handles that allow a solid grip, and both labeled and color-coded as to size for a quick grab.

I had previously purchased a few of these nutdrivers but not the whole set. After using them and then realizing that more and more I needed other sizes too, I decided to purchase the set. The high quality is what brought me back to these. They have a very strong magnet that will not lose it's hold. I had a hard time deciding whether to get these ones or the ones with the longer shank. I ended up settling on these because I realized that the longer ones wouldn't fit too well in the outside pockets of my toolbag, and would be sticking out too much. Didn't want to risk them falling out and losing one somewhere. Bought these and have been using them extensively ever since. As for the ones I bought before these...I gave them to my father to show him the quality and craftsmanship of these wonderful tools. These may seem to be on the pricey side, but I guarantee that you will not regret it and would purchase again if need be. Thanks for reading....Ray.
