## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Works Great with Mac, but check your serial socket gender before ordering.
  

*by B***Y on Reviewed in the United States on January 2, 2015*

Works GREAT with my Macbook Pro with OSX Yosemite. The trick is the FTDI chip inside the cable. Don't forget to DOWNLOAD and install the Mac driver, or you'll think it doesn't work.NOTE:This product (and most like it) has the wrong gender if you're trying to control a Radio or Ham Transciever. Notice most people who buy this also buy the "mini DB9 Female to Female Gender changer? Dummy me... I DIDN't notice and had to make a special run to pick one up locally!The two are sold together if you look at the bottom of the screen. Must be a popular combo for some reason... ;o)

    LOVE these!!! Burn your PL2303!
  

*by M***I on Reviewed in the United States on May 4, 2012*

These are light years easier to deal with than the typical (fake) Prolific chipset units. This particular one is especially nice. There's no clunky box at all- the guts are hiding in the USB plug. So it looks like a straight USB to 9-pin D.FTDI chip support pops up like magic in every Windows, Mac OS X, and Linux I've had a chance to use with it.Thank god there's an alternative to the terrible Prolifics. Their drivers are awful and apparently most of the chips on the market now are cheap semi-functional counterfeits. I can't remember the last time it wasn't a huge hassle getting a PL2303 to work right.If you're using one of these, you're likely sitting on the floor of a colo somewhere desperately trying to fix something important. Do you have time to screw around with your adapter first? I don't.

### ⭐⭐⭐⭐⭐ 







  
  
    Real deal FTDI chipset that works.
  

*by G***D on Reviewed in the United States on December 15, 2017*

If you deal with legacy gear, commonly the case with amateur radio and industrial devices, this is a no-nonsense solution that works.I have some of the knock-off Prolific clones that *can* work with a lot of juggling, but OS updates and portability across PCs is a crapshoot.This is the real deal and will work.  My only suggestion would be to include a F/F DB9 gender changer, as many pieces of hardware like police scanners have a male port on the rear panel.
