Does the job
Does exactly what it's supposed to do. I used it to connect an old EPROM programmer with a 25-pin socket to a USB-serial cable with a 9-pin plug. Works great.

Easy Conversion from DB-9 to DB-25
I've always had good results with StarTech products. This DB-9 to DB-25 adapter is a straight through adapter, in other words, the transmit and receive lines are not crossed like with a crossover cable or null modem adapter. If you only have a DB-9 to DB-9 cable, use it to recreate the old modem cable (DB-9 to DB-25) from the old days. I use mine to feed my PC's USB DB-9 serial converter to the 25 pin parallel port on my old dot matrix printer. I also own a second one. I use it in the same fashion to connect my PC to my old Apple IIe Super Serial card which has a DB-25, 25 pin plug. Wonderful product!

Worked with a modem
Worked with no issues with an old modem. Glad I got it. Will purchase spares just in case.

Good to have one.
It is a bit old fashioned for computer communications but it helps to have one when it is needed.

It works with my modem
I connected it between my modem and my serial cable and it properly adapted the wiring, and even the hardware flow control is properly functioning.

Useful interface from Star Tech
Sturdy 25 way to 9 way, for connecting your 9 way pc port to vintage 25 way port. This is IT speak for this type of connector back in the day.
