## Questions & Answers

**Q: Do they include the plastic backshells shown in the last pic?**
A: The black rectangles in the picture are not plastic nor are they what I would call  ‘backshells’; they’re
thin, foam rubber insulation pads, glued on, intended (I believe) to provide some limited protection to the underside of the circuit board.

### ⭐⭐⭐⭐⭐ Excellent product

Excellent product

### ⭐⭐⭐⭐⭐ Easy to use if you understand RS-232 signals and wiring
*by A***R on January 30, 2021*

They arrived and work as expected. It’s easy to use if you understand RS-232 wiring.Funny that Amazon asks me to rate this product on its “thickness” and “sheerness” and “ease of use”.

### ⭐⭐⭐⭐⭐ I liked them. I used these to make a cable ...
*by J***N on February 21, 2018*

I liked them. I used these to make a cable for my APC uninterruptable power supply, for which i used a hyperterminal like program to access its built in command prompt. I used them to configure how many external batteries the Unit has connected to it. This brand of UPS has some wires switched around in there......non standard serial port..... so this product has screw terminals, allowing you the option to test or move wires around ...or to make new cables at a moments notice, which is very handy. They worked. The standoff/studs are present, so keep in mind of that. They come off, but anyone whom has ever delt with serial ports knows that the studs hold the shroud/sheild metal part on. youd want to glue it or put the proper flat screw through it etc.
