Not much to say about this little guy other then it works. I use it to test signal between control systems (AMX, Crestron) and the devices they control. One thing I would change is to make the pegs removable. Currently if you remove them then the metal around the input and output comes off. My workaround for this is to use gender changers on both end without the pegs.

Quality Value Price - Excellent product, huge AV RS232 control troubleshooting timesaver.

As an AV professional this is an extreme time-saver for RS232/Serial control trouble shooting. It eliminates the guess work of whether TX & RX are swapped and saves you from pulling out your multi-meter and trying to juggle test leads and DB9 cables in your hands with a flashlight. My only problem that myself and others who have reviewed this product have seen is the lug screw issue preventing you from plugging it into a piece of gear such as a TV RS232 port to determine serial TX pinout. This is easily resolved by swapping them with screws. Excellent product, will buy again!!
Quality Value Price - serves its purpose

no information to tell you what light status or color indicates, lights poorly mounted, tilt in multiple directions
was able to use it for my needsQuality Value Price - Should be used by anyone making first time connections to a serial device

Works very well and can save you lots of time connecting to serial devices for the first time. Lets you know if you need a null converter quickly
Quality Value Price - Works fine.

Small and rugged. Shows line activity for trouble shooting RS-232 data lines in the field. Met my needs for testing.
Quality Value Price - Perfect for current nine pin RS-232 testing

These were once hard to find - glad to have them here at Amazon. There are far too many 25 pin RS-232 testers on the market for a connector that's nearly disappeared. I have one of these in every tool kit and at every desk because they are indispensable for figuring out what's going on when a new piece of equipment wanders into the shop.
[Update December 2013]
One of the low-star reviews mentioned that these won't connect to chassis mount connectors that have jack sockets. I commented "Easy, unscrew the jack sockets on the tester". I got three new testers today and did that and the metal shells fell off. Older testers had captive metal shells so you could just unscrew the jack sockets if they get in the way. Today's don't. Four 4-40 screws will take care of it holding the shells on, but the product has changed in an unfortunate way.Quality Value Price - RS232 is still alive

People don't realize that many sensors and I/O devices still use serial connections.
These are great for testing a connection and data flow.Quality Value Price - Excellent - It does what it says it will do

I like some other reviewers know for a fact that serial connectivity is not dead, finding a tester for DB-9 is not off-the shelf available for sure and finding this on Amazon was a blessing. I was in need of a test unit that was inline and simple to use and understand for checking signals from a control panel to an RS-232 external control port to mounted video projectors. I have to ascertain when a projector does not turn on or off from the wall controller if it is the wall controller / wiring, or the projector - if I call the wrong vendor responsible for warranty / repair I have to eat the service call cost. Having a small test unit with a visual indicator makes the diagnosis very simple. I did not find the LED indictors "dim" as some others have mentioned, mine were nice and bright, and exhibited no "bleed over" to the LED next to it. This unit is rugged and does what it says it will do, I did find like some other reviewers that the nuts next to one side of the connector get in the way when not mating to a cable but directly a device, simple to remove however and not a problem at all. I would recommend this to others.
