    I purchase this to replace the XTXL connectors, It was much easier to diagnose a bad circuit,
    For those who wondered the base fit a Molex Euro Style. The only comment is if you use them, make sure that there is no residual tension on the wires so the do not get fatigued or come loose from the connector.

    Xtension connector sets

    I like these for evolving builds where components get swapped out from time to time. Easier and quicker than cutting and re-soldering connections. Keeps the wiring as modular as everything else. They are a little bit bulky however, when used in tight spaces.

    Introduced unnecessary delay in project- my responsibility. Purchased without knowing the dimensions (missing in the ad)

    Xtension Connector Sets are Invaluable

    These connectors allow projects to be wired such that maintenance, repair and replacement do not require cutting and splicing wires to components. Would like to see PCB mounted versions of the socketed end also.
