Great, with one minor issue  Time owned: 0 to 3 months
I purchased the CT-29B for my FT-7800 along with the CT-29A and CT-28A for my FT-60. My first impression based on the CT-29A/28A pair was great. Very well built, the serial-TTL level converter circuit board neatly hidden in the DB9 connector shell, molded-on strain reliefs, etc...and they worked.

Then I tried the CT-29B. It took a couple of hours of troubleshooting to determine that one wire from the cable wasn't soldered correctly onto the tiny circuit board. Basically the insulation had melted, filled the hole and served as a physical anchor - so it looked like it was connected.

To their credit, RT Systems provides some comprehensive serial troubleshooting tips and a small program you can download to search all com ports, determine which port has the cable connected, etc. There were instructions about measuring the voltage on the two lines going to the mini-DIN connector. This is how I found my issue. I could read the correct voltage on the circuit board but couldn't read it at the DIN plug. A simple re-solder of one connection and it worked.

So, I am rating this a 4 out of 5 only because this should have been caught in QA. This wasn't an intermittent connection. RT Systems redeemed themselves by providing all the necessary instructions to track down the problem.

Then I tried the CT-29B. It took about four hours of troubleshooting to determine that one wire from the cable wasn't soldered correctly onto the tiny circuit board. Basically the insulation had melted, filled the hole and served as a physical anchor - so it looked like it was connected.
