10PCS DB9 Female Breakout Connector,DB9 Solderless RS232 D-SUB Serial to 9-pin Port Terminal Adapter Connector Breakout Board with Case Long Bolts Tail Pipe

It was very easy to put together and was very sturdy.

These connectors make if very easy to wire up and later change configurations of the wiring. They work well for my application. The screw terminals make them a little larger so if you have small spaces you need to plug into you may need to take that into consideration, but they are easy to use and eliminate the need to solder or de-solder if you make a mistake with wiring.

This works well. Screws a little soft but have been able to reuse these without trouble. Bulkier than a crimped or soldered connector but very low hastle

They are really practical

The pin numbers and GND silkscreen on the board were very helpful keeping track of which wire goes where. In my application Roboteq HDC-2460 motor controller I was unable to use the 25 pin and 9 pin connectors side by side with the shells on due to the narrow spacing between connectors. I was able to use them by removing both backshells.

I love these breakouts. They're really well made. I had no issues with torqueing anything down. In the past, I've dealt with stripped, cross threaded screws on things like this but no problems here. I also like that they come with various sizes of bushings/clamps to accommodate different #'s and thicknesses of wires.

Used for intended purpose and it worked well

I have used a bunch of these and they are all fine. Easy to assemble. They smell pretty bad though coming out of the packaging.
