These connectors are very good. I buy 2 pin and 9 pin connectors and I will buy more. They are strong, hold the wire well and have a good mechanical finish. They fit well together and snap well, so I don't expect any wiring issues like intermittent contact. (I'm still working on my project.) Also important to me is that with a pin spacing of .200 (5.08mm), multiple connectors can be strung together (stacked or lined up, since the length of each connector is exactly the integral factor of the spacing between i need about 30 positions of screw connectors and they stack up nicely (folded) together. Another review mentions that the pins are .040" square and therefore will not fit in the .040" round hole that most prototype boards are supposed to fit. This is indeed the case. So you either have to push the pin through the hole or change the size of the hole. Holes from loss of via material. I found a very nice clean prototype board with well defined holes and solder pads. worked well because resizing holes and redrilling went smoothly. These boards won't show up, but the vendor's website will show up with some searching.
