For those projects that you can use these for, Cannot be beat. I have been using a fair amount of these on a particular electronic project and without them, I would not be able to make the custom mods I had planned for the circuit. They will allow me to swap out various components and plug in wires on the Printed Circuit Board to achieve the results I am looking for once the system is finished and installed. I have been using these connectors now for several years but always ordered them in limited quantities from another supplier at a much higher cost. It was always a pain sorting through their inventory online to put together enough parts to do much work with small low power circuits.
