Review: Klein does it again - These are heavy duty and designed very well. They are also very large in size which I was not expecting. They are easy to hold onto and are quite versatile. For context, I work in IT and have used these a few times for installing monitors on dental arm mounts and they have worked flawlessly. Definitely worth the money. Klein is my first preference for tools in general because they have been consistently high quality tools for a great value. They also tend to have options that are more aligned with what I am looking for instead of having to buy a larger kit than I need or buy separate kits to get what I need.
Review: Tools - Good durable product easy grip on your hands
