Great tool to make tightening tiny/thin industrial electronics impossible, also good for bike and car maintenance. Because of the time and likely overheating to make them out of a regular "good" adjustable wrench, just buy one in a small, well-made package, convenient, and the handle fits into those hard-to-reach places just fine. DO NOT use this tool. For daily replacement of a regular crescent wrench set it will help where others can't, I would buy longer jaws of this size but the current configuration is quite convenient.
