    Pros: It works

    Cons: Limited stock?

    The quality is fine and the price is great. I had to wait a few months for it to be in stock.

    Eventually gets the job done

    Pros: Sturdy design, quality parts.

    Cons: Pins don't come back out of db9 easily. No simple way to tie two wires to the same pin.

    Overall it got the job done but it took a lot longer than I was expecting to get everything together. Very difficult to remove the pins after inserting them into the db9, so don't make a mistake when configuring your pinout. Also, my particular pinout (cisco console cable) required two of the pins to go to ground, so I had to remove a pin from one of the wires and solder it to the outside of the other pin. Would have been nice if there was an easier alternative for that situation.

    Pros: Good quality, works great, arrived as advertised.

    Cons: No wiring diagram for common pin outs.

    Exactly what I was looking for at a great price. Once again, Monoprice comes through.
