Does a fine job. The pinout coloring could be more clear, but once you know it, it's fine, and you can always look it up. Made a mistake, but a paper clip can push it back out. I wouldn't recommend doing it many times, I'm sure it'll weaken everything.
One thing would be nice is ability to buy a version that includes shorting and splitting data lines. Some pinouts call for this. E.g., shorting Data Carrier Detect (DCD) and Ready to Send (RTS).
PROS: Easy to use. Can re-set/push out with a paperclip if necessary (not recommended)
I used these adapters to make straight-through cables, null-modem, roll-over, and APC UPS compatible cables. Some required soldering, but the modular setup of these adapters made setting up custom pin-outs a breeze.
I was especially interested to begin a relationship with this company as my son, who buys here frequently and in quantity, recommended the firm. His impression is correct: Lots of useful products, quick shipment, top service.
PROS: Quick, accurate, simple. The product was lost at my end and, when I contacted Monoprice to see if it had been lost in shipment, I got quick, intelligent and courteous answers.
