These were a great addition to my rc drift car to get the wiring connected in a clean fashion to have a clean flawless install. The length of them is very accurate and will probably suit most applications. I used the longest one that came with it and for my use it was perfect. Great fit on the connectors. Works just as described and will help clean up your install on most projects you are working on, and the bonus is that you have one maybe for your next build that will work out.
